Feature request: Boot default subvolume in BTRFS

Feature request: Boot default subvolume in BTRFS

Hello,

this is the description of my feature request:
Grub is booting the default subvolume in BTRFS w/o any manual
modification in Grub configuration.

Current situation:
Booting a snapshot created with Snapper
<https://wiki.archlinux.org/index.php/Snapper> is not possible w/o
modifying the Grub entries.
This is related to the Snapper functionality that creates a ro snapshot
that must be booted and then creates another rw snapshot of the
currently booted ro snapshot. Then Grub configuration must be recreated
to reflect the newly created rw snapshot.

Available solution:
In OpenSuse Grub is always booting the default snapshot and hereby Grub
configuration must not be adjusted.
To my understanding OpenSuse uses a patched Grub.

Regards
Thomas

I will send those patches to the mailing list once they are polished for
review. 

Thanks,
