Recommended Btrfs Assistant configuration

[Leya]

Then this part is optional but I should do this:

You may wish to add GRUB_BTRFS_SNAPSHOT_KERNEL_PARAMETERS="rd.live.overlay.overlayfs=1" to /etc/default/grub-btrfs/config for booting snapshots read only. See here for more information about that: https://github.com/Antynea/grub-btrfs/blob/master/initramfs/readme.md#dracut-based-distros

Afterward, regenerate a new snapshot submenu.

sudo /etc/grub.d/41_snapshots-btrfs

Reboot and test that you are able to boot to a snapshot from Grub.

I think this is no longer necessary:

@dalto

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.

But I guess there is no harm in having it added either.
