`grub-btrfs` configuration

[dzamlo]

In /etc/default/grub-btrfs/config, the GRUB_BTRFS_GRUB_DIRNAME parameter need to be set to the folder containing the generated grub.cfg which will depend on the mount point of the ESP partition par default (so "/efi/grub" by default).

In theory, GRUB_BTRFS_ENABLE_CRYPTODISK should also be set to "true" if the root partition is encrypted. Unfortunately it doesn't work on my config, with both the default version and the grub-btrfs-git from the AUR, but I believe the issue is with grub-btrfs not your tool. I need to investigate this point.

https://github.com/Antynea/grub-btrfs/blob/master/config - Perhaps we can find something here ?

My thought is that you are trying to do seperate /boot encrypted + /efi ? related to your other issue (grub wiki page also mention to put it on a simpler filesystem, ie not btrfs)

My second guess i that you want some kind of snapshots ? I don't know much about these (aside from fixing them last time: archlinux/archinstall@375d64a) so any digging is welcome really.

My end goal is to have bootable snapshots working with disk encryption and not failing on kernel update. We are nearly there.

There are two bugs in grub-btrfs that I reported (Antynea/grub-btrfs#417 and Antynea/grub-btrfs#416).

From your installer there are two things to do in /etc/default/grub-btrfs/config:

• set GRUB_BTRFS_GRUB_DIRNAME to the directory where the generated grub.cfg is stored. On my installation this is the grub subfolder of the ESP partition (so "/efi/grub").
• setting GRUB_BTRFS_ENABLE_CRYPTODISK="true" if the root partition is encrypted.

Cool I've got the patch for this ready and watch listed their repo for when it drops (or ping here whenever).

I can also already merge #86 (for parent issue) after some more tests (but have done a lot of installs today, so I'm calling it for today) Again thanks so much for the digging
