 Hi,
 
 this patch series improves the way /usr filesystems are handled: tag
 them appropriately, so later on we can find them and merge results they
 contain directly back for the root filesystem.
 
 The series includes also a new private debug API, and its usage to fix
 the resolution of /dev/mapper/.. devices found in fstab; without it,
 LVM /usr filesystems are not recognized as belonging to their roots.
 Maybe a better API for this could be added, but since it's something
 only related to the appliance then can stay internal for now. (Better
 suggestions always welcome, of course.) 
Firstly, I still think we need:
  [PATCH 1/2] inspect: fstab: Canonicalize paths appearing in fstab.
although it's not related to the current patch series.
In regards to this series:
 Pino Toscano (5):
   inspect: change is_root flag into enum
   inspect: mark CoreOS /usr partitions with own USR role 
These are fine.
   daemon: debug: new "exists" subcommand
   inspect: fix existance check of /dev/mapper devices 
This is very ugly.  We really shouldn't be calling a debug API from
inspection code.
   inspect: gather info from /usr filesystems as well (RHBZ#1401474)
I have specific comments on this patch.
Rich.
