[Bug 1961079] Re: [Ubuntu 22.04] Allow ESP installation on md-disks in subiquity

[Vinay HM]

Hi dbungert,

To do so, please boot
https://releases.ubuntu.com/jammy/ubuntu-22.04.2-live-server-amd64.iso
with kernel command line
subiquity-channel=beta/lp-1961079

At the "Installer update available" screen, allow the update to
proceed. Continue the install as normal

--> I have tried installing 22.04.2 by passing "subiquity-
channel=beta/lp-1961079" kernel parameter. But as you said above, I did
not get any request to update at installer level. It is proceeding like
normal installation and disks are detected as normal nvme drives not as
md-raid disks.

PFA of installer logs.

Bug description:
  subiquity installer currently does not allow to select md-disk as Installation destination where /, /home and /boot/efi could be created and installed. 
  Request is to enable this feature so that we can install and boot from md-disk, which our BIOS creates.
