Hallo, Chris,

Du meintest am 19.06.12:

I'm trying to figure out an algorithm from taking an arbitrary
mounted btrfs directory and break it down into:

<device(s), subvolume, subpath>

where, keep in mind, <subpath> may not actually be part of the
mount.

Do you want an API for this, or is it enough to wander through
/dev/disk style symlinks?

The big reason it isn't here yet is because Kay had this neat patch
to blkid and udev to just put all the info you need into /dev/btrfs
(or some other suitable location).  It would allow you to see which
devices belong to which filesystems etc.

"btrfs" should work even without any "udev" installation.

Viele Gruesse!
Helmut
