So, this is the file-system value that I'm using currently for the
store. The information about subvolume is in the options value.
(file-system
(device (uuid "84fc6b78-d7ff-45df-8659-bef44b5bf0ea"))
(type "btrfs")
(title 'uuid)
(mount-point "/gnu/store")
(needed-for-boot? #t)
(options "subvol=/gnu/store"))
I guess one approach for dealing with this would be to allow directly
configuring the stripping of the mount point somehow. Or maybe having
some btrfs-file-system record, which could store the subvol option in a
more machine readable way.
One thing that still makes me uncertian, is how grub actually is trying
to find files on the btrfs filesystem. I tried changing the default
subvolume to the one containing the store, but that didn't seem to
help. Looks like it might not be aware of subvolumes.
