-Regression test on virt-inspector

-Occasionally we break virt-inspector through some change.  We should
-add a regression test for it.  However this is hard because we'd need

-Update: I managed to fit a real-but-minimal Fedora 13 image into 6.2 MB.

+More ntfs tools
+---------------
+
+ntfsprogs actually has a lot more useful tools than we currently
+use.  Interesting ones are:
+
+ntfslabel: display or change filesystem label (we should unify all
+  set*label APIs into a single set_vfs_label which can deal with any
+  filesystem)
+
+ntfsclone: clone, image, restore, rescue NTFS
+
+ntfsinfo: print various information about NTFS volume and files
+
+ntfs streams: extract alternate streams from NTFS files
+
+ntfsck: checker for NTFS filesystems
+
+Undelete files
+--------------
+
+Two useful tools:
+
+  - ext2undelete
+  - ntfsundelete
+
+More mkfs_opts options
+----------------------
+
+Useful options to offer:
+ - Set label.
+ - Set UUID.
+
+Use /proc/self/mountinfo
+------------------------
+
+This file contains lots of interesting information about
+what is mounted and where. eg:

 
 

-guestfish -i livecd.iso
+  16 21 0:3 / /proc rw,relatime - proc /proc rw
+  17 21 0:16 / /sys rw,relatime - sysfs /sys rw,seclabel
+  18 23 0:5 / /dev rw,relatime - devtmpfs udev rw,seclabel,size=1906740k,nr_inodes=476685,mode=755
+  26 21 253:3 / /home rw,relatime - ext4 /dev/mapper/vg-lv_home rw,seclabel,barrier=1,data=ordered

 
 

-Could this be done through the core API and existing calls?
+This could be used instead of current hairy code to parse the output
+of the 'mount' command.  We could add new APIs to return kernel mount
+options, type of filesystem at a mountpoint etc.
