No actual hard drives were harmed in the production of this blog post. The examples are easier to read if you turn your smart phone sideways. Command Line Is Faster Sure you can partition your discs using a GUI disk management application or an interactive, menu-driven terminal interface. But the command line is faster. gdisk vs sgdisk sgdisk is the scriptable version of gdisk (gptfdisk). what the manpage says If you\u2019re familiar with gdisk , you probably know how to interactively set the partition size and type. If you look at the man page for sgdisk you see that the relevant flags are -n and -t . The beginning and ending numbers are absolute, unless you prepend them with a + or - sign, in which case they become relative. # For New Partition: -n, --new=partnum:start:end # Change partition type: -t, --typecode=partnum:{hexcode|GUID} Example with Separate EFI and / Partitions BTW, gdisk is a partitioning tool intended to be used with a gpt partition table, so the assumption is that you would want an efi partition, (although the efi partition does not have to be on the disk you are partitioning or even on the same disk where your other system partitions are). Wipe any leftover filesystem metadata with wipefs. wipefs --all /dev/sdx Create a new GPT partition table. sgdisk /dev/sdx -o Create an efi partition of 512MB by specifying the end of the partition (relative) and the partition type, ef00 . sgdisk /dev/sdx -n 1::+512MiB -t 1:ef00 Create an / partition using the remainder of the disk, by not specifying the end or the beginning or partition type, which defaults to 8300. sgdisk /dev/sdx -n 2 Format the efi partition fat 32. mkfs.vfat -F32 /dev/sdx1 Format the / partition ext4. mkfs.ext4 /dev/sdx2 Practice With A Sparse Image If you don\u2019t want to partition a real hard drive, you can practice using an sparse image file, instead. # create a sparse image file truncate -S 100G practiceImage.img # partition the image file with sgdisk sgdisk practiceImage.img -o # etc Example with Separate /boot, EFI, and luks-encrypted / Partitions Wipe any leftover filesystem metadata with wipefs . wipefs --all /dev/sdx Create a new GPT partition table. sgdisk /dev/sdx -o Create an efi partition of 512MB by specifying the end of the partition (relative) and the partition type, ef00 . sgdisk /dev/sdx -n 1::+512MiB -t 1:ef00 Create a /boot partition of 1GB, by specifying the end of the partition (relative), but not specifying the partition type which defaults to 8300 . sgdisk /dev/sdx -n 2::+1GiB Create an / partition using the remainder of the disk, by not specifying the end or the beginning or partition type, which defaults to 8300 . sgdisk /dev/sdx -n 3 Format the efi partition fat 32. mkfs.vfat -F32 /dev/sdx1 Format the /boot partition ext4. mkfs.ext4 /dev/sdx2 Encrypt the / partition. cryptsetup -y -v luksFormat --type luks2 /dev/sdx3 Decrypt the / device. cryptsetup open /dev/sdx3 cryptroot Format the / device. mkfs.xfs /dev/mapper/cryptroot What About Swap? I prefer to use a swap file inside the luks-encrypted / partition. But you can make a separate swap partition if you like. Example with 2GB swap partition Wipe the disc. wipefs --all /dev/sdx Create a new GPT partition table. sgdisk /dev/sdx -o Create an EFI partition. sgdisk /dev/sdx -n 1::+512MiB -t 1:ef00 Create a /boot partition. sgdisk /dev/sdx -n 2::+1GiB Create a / partition with a relative negative end. sgdisk /dev/sdx -n 3::-2GiB Create a swap partion type 8200 . sgdisk /dev/sdx -n 4 -t 4:8200 format the partitions. mkfs.vfat -F32 /dev/sdx1 mkfs.ext4 /dev/sdx2 mkfs.xfs /dev/sdx3 mkswap /dev/sdx4 Conclusion Good luck to you.

The result is quite pleasant: the stability of desktop Debian, but with the rough edges polished smooth, nicely configured fonts and ui, and all the multi-media codecs included. Previously, I wrote a guide for installing LMDE3 with disk encryption . The installer for LMDE 4 is different in that it includes support for disk encryption, but not if you need custom partitions such as for a dual-boot configuration . With this in mind, the examples presented below assume that you have Windows 10 installed in 4 partitions, and thus you would want to make 3 partitions (5,6,7) after that, for LMDE4. As with before, with separate partitions for /boot formatted ext4, /boot/efi formatted fat32, and a regular luks-encrypted partition for / formatted xfs. With a separate efi partition for LMDE4, you can then use the computer's device boot menu to select which efi boot entry you want to boot. There is also an advantage in having Windows use the first efi partition, in that if something happens to the Windows efi boot entry, you can fall back to the default efi executable. Whereas, if the efi boot entry for Linux somehow gets wiped, you could repair that easily enough via chroot .

The fourth page of the live-installer covers name, password, and hostname. After this select manual partitioning . On the seventh page of the live-installer, you come to a partition configuration page. But there is nothing to do here. The partition-configuration doesn't even recognize your encrypted partitions. But no matter, because you have already mounted the target file system relative to /target/ , so select expert mode at the bottom of the page. the installer doesn't even recognize the encrypted partitions ... ignore everything on this screen and click the `Expert mode` button Again select forward , and when you come to the page where you configure the location to install grub, that should be the efi partition, i.e. /dev/sda5 . select the efi partition as the location to install grub Then continue with the installation. The installation will run for a few minutes and will then pause. There will be a popup informing you that the installation has paused.

UEFI Fix Well, actually there isn't one. In this scenario having two efi partitions, we rely on the motherboard correctly persisting efi boot entries. So if you are unlucky enough to have one of the HP laptops that forgets efi boot entries, I guess you are out of luck. You might try using a single efi partition instead of two, and maybe that will work. Presumably this would require using VeraCrypt for Windows, instead of Bitlocker (because Bitlocker won't allow Grub to load the Windows bootloader?)

The result is quite pleasant: the stability of desktop Debian, but with the rough edges polished smooth, nicely configured fonts and ui, and all the multi-media codecs included. Previously, I wrote a guide for installing LMDE3 with disk encryption . The installer for LMDE 4 is different in that it includes support for disk encryption, but not if you need custom partitions such as for a dual-boot configuration . With this in mind, the examples presented below assume that you have Windows 10 installed in 4 partitions, and thus you would want to make 3 partitions (5,6,7) after that, for LMDE4. As with before, with separate partitions for /boot formatted ext4, /boot/efi formatted fat32, and a regular luks-encrypted partition for / formatted xfs. With a separate efi partition for LMDE4, you can then use the computer's device boot menu to select which efi boot entry you want to boot. There is also an advantage in having Windows use the first efi partition, in that if something happens to the Windows efi boot entry, you can fall back to the default efi executable. Whereas, if the efi boot entry for Linux somehow gets wiped, you could repair that easily enough via chroot .","title":"Introduction"},{"location":"posts/lmde4-custom-partitions-disk-encryption/#prepare-the-installation-media","text":"Visit the Linux Mint Website and download the iso file for LMDE 4 64bit.

In case you are not familiar with svg , scalable vector graphics, it is an image that is completely rendered from a string of text, or more accurately XML text, unlike PNG or JPG , which are binary file s. Python Libraries Used BeautifulSoup to consume html CairoSVG to convert svg to png python-pillow to convert transparent png background to white opencv-python to extract data from qrcode python-pyotp Form ScreenShot This is the form we will be testing. In real life you would confirm that you want to use two-factor-authentication by scanning the qrcode with an authentication app on your smartphone, and then enter the time-based one-time password . totp codes are derived from two things and two things only. A secret key and a time such as the current time. For instance, an authentication application can tell you what your totp code is, but of course in this testing scenario we use python-pyotp , after extracting the secret key from the qrcode. enable totp confirmation form Import Python Libraries # tp/accounts/tests/test_enable_totp_view.py # python manage.py test accounts.tests.test_enable_totp_view from django.test import TestCase from django.contrib.auth.models import User from accounts.models import Account from django.urls import reverse from bs4 import BeautifulSoup import cv2 from cairosvg import svg2png from PIL import Image import pyotp import pathlib The Account model has a one-to-one relationship with the Django built-in User model.

The result is quite pleasant: the stability of desktop Debian, but with the rough edges polished smooth, nicely configured fonts and ui, and all the multi-media codecs included. Unfortunately, the LMDE 3 installer does not support disk encryption, but manually setting this up by hand is pretty straightforward. On the other hand, manually setting up your partitions by hand allows extra freedom and flexibility, and so I have chosen a simple luks-encrypted / partition formatted xfs. As far as swap is concerned, my preference is to use a swap file instead of a swap partition. Having a swap file instead of a swap partition is more flexible because obviously you can easily recreate a different size swap file whenever you like (or use none at all), and the encryption requires no extra set up because the / partition is encrypted anyway. Will this work with a dual-boot set up? Of course! Because you have to manually configure the partitions anyway, just arrange them exactly how you would need for dual-boot. Assumes uefi-configured boot, with separate partitions for /boot formatted ext4, /boot/efi formatted fat32, and a regular luks-encrypted partition for / formatted xfs. Prepare The Installation Media Visit the Linux Mint Website and download the iso file for LMDE 3 64bit. Download from torrents if possible, to save bandwidth. verify the sha256 sum of the iso file sha256sum lmde-3-201808-cinnamon-64bit.iso Identify the thumb drive you are going to install from. type lsblk , note the output, and then insert the thumb drive then type lsblk again and note the additional output # lsblk /dev/sdb NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sdb 8:32 1 14.5G 0 disk \u251c\u2500sdb1 8:33 1 3.4G 0 part /media/trent/Debian 9.6.0 amd64 \u2514\u2500sdb2 8:34 1 416K 0 part In the above example output we see that our thumb drive is identified as /dev/sdb , and partition /dev/sdb1 is automatically mounted. Take special care that you have accurately identified the thumb drive before proceeding. For the sake of example, we will proceed on the assumption that our thumb drive is identified as /dev/sdb , but you need to compensate accordingly. unmount any partition of the thumb drive that are automatically mounted umount /dev/sdb1 write the disk image to the thumb drive ddrescue -D --force lmde-3-201808-cinnamon-64bit.iso /dev/sdb Boot The Install Disc boot into bios to disable fastboot and secureboot invoke your machine's device boot menu and boot the install disc in uefi mode confirm that you have booted in uefi mode by listing efivars ls /sys/firmware/efi/vars Partition The Hard Drive If you recall we are assuming the target hard drive is /dev/sda , as an example. So, make adjustments as necessary. If you would rather use a different partition tool, make sure the efi partition is an efi partition type, and you definitely need a separate /boot partition. if needed you can clear the drive with wipefs wipefs --all /dev/sda create a new partition table for /dev/sda sgdisk /dev/sda -o create a new efi partition for /dev/sda sgdisk /dev/sda --new=1::+512MiB --typecode=1:ef00 create a new /boot partition for /dev/sda sgdisk /dev/sda --new=2::+1G create a new / partition for /dev/sda sgdisk /dev/sda --new=3 verify your partition work sgdisk /dev/sda -p format the efi partition mkfs.vfat -F32 /dev/sda1 format the /boot partition mkfs.ext4 /dev/sda2 encrypt the / partition, you will be prompted for a password cryptsetup -y -v luksFormat --type luks2 /dev/sda3 decrypt the / partition, you will be prompted for a password cryptsetup open /dev/sda3 cryptroot format the / device mkfs.xfs /dev/mapper/cryptroot Mount The Hard Drive This takes advantage of expert mode in the LMDE installer. create an /target directory mkdir /target mount the / device at /target mount /dev/mapper/cryptroot /target create an /target/boot directory mkdir /target/boot mount the /boot partition at /target/boot mount /dev/sda2 /target/boot create an /target/boot/efi directory mkdir /target/boot/efi mount the efi partition at /target/boot/efi mount /dev/sda1 /target/boot/efi Run The Installer App At this point you're ready to run the live installer. You can click the disc icon on the desktop. The first three pages of the live-installer cover Language,Timezone, and Keymap. The fourth page of the live-installer covers name, password, and hostname. On the fifth page of the live-installer, you come to a partition configuration page. But there is nothing to do, so select expert mode at the bottom of the page. Again select forward , and when you come to the page where you configure the location to install grub, that should be the efi partition, i.e. /dev/sda1 . Select forward one more time, and then select install. The installation will run for a few minutes and will then pause. During the pause you need to manually configure fstab and crypttab .

Unfortunately, the LMDE 3 installer does not support disk encryption, but manually setting this up by hand is pretty straightforward. On the other hand, manually setting up your partitions by hand allows extra freedom and flexibility, and so I have chosen a simple luks-encrypted / partition formatted xfs. As far as swap is concerned, my preference is to use a swap file instead of a swap partition. Having a swap file instead of a swap partition is more flexible because obviously you can easily recreate a different size swap file whenever you like (or use none at all), and the encryption requires no extra set up because the / partition is encrypted anyway. Will this work with a dual-boot set up? Of course! Because you have to manually configure the partitions anyway, just arrange them exactly how you would need for dual-boot.

Previously, I wrote a guide for installing LMDE3 with disk encryption . The installer for LMDE 4 is different in that it includes support for disk encryption, but not if you need custom partitions such as for a dual-boot configuration . With this in mind, the examples presented below assume that you have Windows 10 installed in 4 partitions, and thus you would want to make 3 partitions (5,6,7) after that, for LMDE4. As with before, with separate partitions for /boot formatted ext4, /boot/efi formatted fat32, and a regular luks-encrypted partition for / formatted xfs. With a separate efi partition for LMDE4, you can then use the computer's device boot menu to select which efi boot entry you want to boot. There is also an advantage in having Windows use the first efi partition, in that if something happens to the Windows efi boot entry, you can fall back to the default efi executable. Whereas, if the efi boot entry for Linux somehow gets wiped, you could repair that easily enough via chroot .

In case you are not familiar with svg , scalable vector graphics, it is an image that is completely rendered from a string of text, or more accurately XML text, unlike PNG or JPG , which are binary file s. Python Libraries Used BeautifulSoup to consume html CairoSVG to convert svg to png python-pillow to convert transparent png background to white opencv-python to extract data from qrcode python-pyotp Form ScreenShot This is the form we will be testing. In real life you would confirm that you want to use two-factor-authentication by scanning the qrcode with an authentication app on your smartphone, and then enter the time-based one-time password . totp codes are derived from two things and two things only. A secret key and a time such as the current time. For instance, an authentication application can tell you what your totp code is, but of course in this testing scenario we use python-pyotp , after extracting the secret key from the qrcode. enable totp confirmation form Import Python Libraries # tp/accounts/tests/test_enable_totp_view.py # python manage.py test accounts.tests.test_enable_totp_view from django.test import TestCase from django.contrib.auth.models import User from accounts.models import Account from django.urls import reverse from bs4 import BeautifulSoup import cv2 from cairosvg import svg2png from PIL import Image import pyotp import pathlib The Account model has a one-to-one relationship with the Django built-in User model.

Consume SVG with BeautifulSoup class TestEnableTOTPViewTestCase ( TestCase ): ... def test_enable_totp_view ( self ): ... soup = BeautifulSoup ( get_response . content , features = \"lxml\" ) svg_container = soup . find ( \"div\" , { \"id\" : \"svgcontainer\" } ) self . assertIsNotNone ( svg_container ) scsvg = svg_container . findChild ( \"svg\" , recursive = False ) self . assertIsNotNone ( scsvg ) with open ( 'qr.svg' , 'w' ) as f : x_string = \" \\n \" f . write ( x_string + str ( scsvg )) The inline xml for the svg comes to us as a child of a div with an id of svgcontainer .
