Remote access "waiting for initialization"

[Sithuk]

I'm working on incorporating luks to the ubuntu zfsbootmenu install script. I've hit an issue with remote access that I hope someone can help with.

I've added agorgl's luks unlock script as a zfsbootmenu hook in early-setup.d. Link below to the script.
https://github.com/agorgl/zbm-luks-unlock

The unlock script works as expected. However, I encounter a problem when I add remote access and connect via ssh. ZFSBootMenu starts when I type "zfsbootmenu" in the ssh session, but I get a "Waiting for ZFSBootMenu initialization" screen. I suspect this is because the unlock script has been run as part of the boot sequence and it has not concluded as it is waiting for a password to be entered. One of the aims of remote access is to allow for ZFSBootMenu access when there is no local access. Is there a way to shutdown the script that is run by the hook or to override it to allow ZfsBootMenu to be started from ssh session?

I have already tried running the luks-unlock script and it completes successfully from the ssh session. I just can't get into ZFSBootMenu to select the zpool and boot the system.

Can anyone offer any suggestions?

That script is blocking at a fairly early position in zfsbootmenu-init . You can probably safely run /libexec/zfsbootmenu-init from your SSH session, but it's not really designed with that usage in mind so it could have unintended consequences.

This should be resolved when #599 lands.

Fast work, thank you.

@ahesford : Do you have a roadmap for the next zfsbootmenu release that will have the fix? I would like to release the luks update for the ubuntu zfsbootmenu install script before Ubuntu 24.04 is released (April 25).

[zdykstra]

There's no set schedule for our releases. We've potentially collected enough changes and fixes to warrant one.

I've almost finished testing with 24.04 for the ubuntu zfsbootmenu install script. I'm currently pulling zfsbootmenu from master to get the remote access fix #599. I know you have said previously that pulling from master can introduce problems. Can you foresee any significant issues with using master until you release a new version of zfsbootmenu with #599 ?
