Title:
  no USERDATA space under rpool when installing with ZFS

Status in subiquity:
  Triaged
Status in ubuntu-desktop-provision:
  New

Bug description:
  I'm not sure if this is a bug or if we need to update the isotracker
  test case for this with the new installer, but the test case has this
  command and output:

  $ zfs mount | sort
  bpool/BOOT/ubuntu_UUID /boot
  rpool/ROOT/ubuntu_UUID /
  rpool/ROOT/ubuntu_UUID/srv /srv
  rpool/ROOT/ubuntu_UUID/usr/local /usr/local
  rpool/ROOT/ubuntu_UUID/var/games /var/games
  rpool/ROOT/ubuntu_UUID/var/lib/AccountsService /var/lib/AccountsService
  rpool/ROOT/ubuntu_UUID/var/lib/apt /var/lib/apt
  rpool/ROOT/ubuntu_UUID/var/lib/dpkg /var/lib/dpkg
  rpool/ROOT/ubuntu_UUID/var/lib/NetworkManager /var/lib/NetworkManager
  rpool/ROOT/ubuntu_UUID/var/lib /var/lib
  rpool/ROOT/ubuntu_UUID/var/log /var/log
  rpool/ROOT/ubuntu_UUID/var/mail /var/mail
  rpool/ROOT/ubuntu_UUID/var/snap /var/snap
  rpool/ROOT/ubuntu_UUID/var/spool /var/spool
  rpool/ROOT/ubuntu_UUID/var/www /var/www
  rpool/USERDATA/root_0y7dio /root
  rpool/USERDATA/u_0y7dio /home/u

  However after doing a zfs install with the new installer, I get this:

  ubuntu at ubuntu:~$ zfs mount | sort
  bpool/BOOT/ubuntu_srikxd        /boot
  rpool/ROOT/ubuntu_srikxd        /
  rpool/ROOT/ubuntu_srikxd        /snap
  rpool/ROOT/ubuntu_srikxd/srv    /srv
  rpool/ROOT/ubuntu_srikxd/usr/local  /usr/local
  rpool/ROOT/ubuntu_srikxd/var/games  /var/games
  rpool/ROOT/ubuntu_srikxd/var/lib/AccountsService  /var/lib/AccountsService

  rpool/ROOT/ubuntu_srikxd/var/lib  /var/lib
  rpool/ROOT/ubuntu_srikxd/var/log  /var/log
  rpool/ROOT/ubuntu_srikxd/var/mail  /var/mail
  rpool/ROOT/ubuntu_srikxd        /var/snap/firefox/common/host-hunspell
  rpool/ROOT/ubuntu_srikxd/var/snap  /var/snap
  rpool/ROOT/ubuntu_srikxd/var/spool  /var/spool
  rpool/ROOT/ubuntu_srikxd/var/www  /var/www

  rpool has no USERDATA

  I've been doing install tests this week with the legacy installer too
  and this is not the case for the legacy installer.

  Again I'm not exactly sure if this is intended behaviour but if it is these testcases need updating:
  http://iso.qa.ubuntu.com/qatracker/milestones/446/builds/287565/testcases/1784/results

  http://iso.qa.ubuntu.com/qatracker/milestones/446/builds/287581/testcases/1790/results
  The second testcase is for the legacy test suite, however presumably for 24.04 zfs+encryption will be on offer in the new installer, and this testcase will also need updating as it mounts
  rpool/USERDATA/user_hash
