Eos-dracut 1.2 and grub btrfs snapshot booting

For those of you who like to boot off of you btrfs snapshots using grub, eos-dracut 1.2 now contains support for adding an overlayfs when the root filesystem is a read-only btrfs snapshot.

This does not require any special configuration.

Once you update eos-dracut and rebuild your boot images, any future snapshots will automatically support the overlay.


Will something like this also become possible for systemd-boot?

It would be possible to add this support for systemd-boot but it wouldn’t currently be useful since systemd-boot can’t properly boot snapshots in the first place.

It would take some significant development to get systemd-boot able to boot snapshots on Arch since old kernel versions are not maintained.

thx @dalto :ok:
