Issue mounting zfs home pool shared between stratas

[TheOneWithTheBraid]

I'm using bedrock with a hijacked Ubuntu strata which was initially installed on a zfs root with a separated /home and /home/$USER. It was not causing any issues till I fetched an arch strata and booted using arch's /sbin/init instead of Ubuntu's one.

Now, it's just skipping to mount my /home/$USER zfs and created an empty /home/$USER every boot. I already tried disabling the share of /home but it didn't help. My current workflow is:

• login

  cd /home
  rm -rf $USER
  sudo zfs mount rpool/USERDATA/home/$USER_$GUID
  logout

• login again

It there any easier way?

To make sure I understand correctly:

• Provided you boot with Ubuntu's init, everything works as desired.
• If you boot with Arch's init, /home/$USER is not being mounted automatically.
  • You can manually mount /home/$USER yourself to work around the issue.

Is that correct?

Bedrock can make a lot of things work between strata, but init hooks aren't one of them. Ubuntu's init knows to do zfs setup, but Arch's might not. Bedrock makes Ubuntu's zfs command accessible, but it doesn't teach Arch's init to use it.

I have two ideas:

• The quick and dirty solution is to just make your own systemd unit file which does what you were doing manually. Presumably it'd include something like Exec=/bedrock/cross/bin/zfs mount rpool/USERDATA/home/$USER_$GUID
• There's probably a proper way to teach Arch's init about zfs. Presumably it's covered here somewhere.
