Install SolusOS with software raid0 /home device

I don't know if this is correct or not, but it's working for me. First, torrent/download the latest iso and write it to a thumb drive with ddrescue

ddrescue -D --force Solus-1.2.1.iso /dev/sdX

On my machine you can write the thumb drive using USB 3, but you have to afterwards move the thumb drive over to a USB 2 port to uefi-boot. At boot time on Asus X99 mobo, tap the f8 key for boot device menu, and select uefi-usb.

The SolusOS installer will insist on formatting the / partition, so back that up, and then mdadm is not installed so you will have to install that.

eopkg install mdadm

If you need to create your software raid device, the Arch Wiki is a great resource, but you'll at least need to assemble the raid.

mdadm --assemble --scan

Now you can run the installer gui application, and select the raid device as your home partition. But afterwards there is some additional configuration you'll need to do via chroot. Mount your / device and chroot into it.

mount /dev/sdxY /mnt

or in case of nvme / device

mount /dev/nvme0n1p1 /mnt # (or similar)

and then perform chroot

for i in /dev /dev/pts /proc /sys /run; do sudo mount -B $i /mnt$i; done
chroot /mnt

and then install and set up mdadm

eopkg install mdadm
mdadm --detail --scan >> /etc/mdadm.conf

and then you might want to adjust fstab

# UUID=0421c6.......dd6ecc7     /home   ext4    discard,rw,relatime,errors=remount-ro   0      2
UUID=0421c6.......dd6ecc7     /home   ext4    rw,relatime,stripe=256,data=ordered   0      2

There doesn't seem to be an update-initramfs commmand available, so not sure if raid / device is possible.
