Re: installer no longer signals success or offer reboot

[Mathieu Othacehe]

Hey,

> I can reproduce this issue on a VM, I'm currently investigating it.

Ok, found it, it's the cow-store umount bitting again. As a reminder,
once the installation is over, we need to umount the cow-store overlay
in order to be able to umount to underlying media which Guix is
installed upon.

The problem is that, some processes that run during the installation can
open store files (from the overlay) and keep them open. That's why I'm
trying to kill them before umounting the overlay.

Here the issue is that, after the cow-store is mounted, kmscon opens a
font file from the store. So I'm basically killing kmscon and hence
restarting the installation, not great.

I feel a bit stuck here, I cannot find an alternative to overlayfs and
on the other hand umounting the overlay is problematic.

Do people have some ideas here?

Thanks,

Mathieu
