(gnu build file-systems) is where “fsck.foo” is invoked, in
‘check-file-system’.

The other place to look at is ‘base-initrd’ in (gnu system
linux-initrd), where the ‘helper-packages’ variable hosts packages to be
added to the initrd.

If you adjust these two things, it should be possible to boot on a Btrfs
file system.

However note that there’s an ext2 superblock parser in (gnu build
file-systems), which is used to find partition labels and so on.  This
won’t work on Btrfs partitions I suppose, so you’ll have to refer to
them by device name rather than by label or UUID.

I think I’d rather avoid it by default.  Users can still add it to their
‘packages’ field.

Now, we could add it in (gnu system install) so people can create Btrfs
partition from the installer.  That should be a separate commit, though.

The MUA ate the patch!  It seems lines were wrapped or something.  Could
you send it again, the gnu/packages part?

Also, it would be great if you could try to write a commit entry in
ChangeLog format; see

Thank you!
