What is the use case?  Just having btrfs utilities to manage Btrfs file
systems, or is there some problems to avoid?  I know that for NFS you
must add nfs-utils so that the util-linux provided 'mount' is able to
mount NFS shares.

If the later is the use case, perhaps we could try to hard reference to
each file system utility in util-linux, instead of having it dispatch
some tool supposed to be in the PATH?  I'm not sure how difficult that
would be, and it'd for sure increase the size of util-linux, but perhaps
the pros outweighs the cons.
