-BufferIn
---------
-
-BufferIn should turn into <char *, int> and simple strings in other
-languages that can handle 8 bit clean strings.
-
-Limit on transfers would still be 2MB for these types.

-Equip guestfish with some standard images that it can load
-quickly, eg:
-
-  load ext2

-Maybe it's better to create these on the fly?

+Mount filesystems by UUID or label.  (I'm not really sure if we can do
+this at the moment but we ought to be able to do it, and perhaps make
+it easier by having a direct command).

+Map filesystems to disk blocks

+Map files/filesystems/(any other object) to the actual disk
+blocks they occupy.

+And vice versa.

+Integration with host intrusion systems

+Perfect way to monitor VMs from outside the VM.  Look for file
+hashes, log events, login/logout etc.

+Tips for new users in guestfish
+-------------------------------
+
+$ guestfish
+Tip: You need to 'add disk.img' or 'alloc disk.img nn' to make a new image.
+Type 'notips' to disable tips permanently.
+><fs> add mydisk
+Tip: You need to type 'run' before you can see into the disk image.
+><fs> run
+Tip: Use 'list-filesystems' to see what filesystems are available.
+><fs> list-filesystems
+/dev/vda1
+Tip: Use 'mount fs /' to mount a filesystem.
+><fs> mount /dev/vda1 /
+Tip: Use 'll /' to view the filesystem or ...
+><fs> ll /

+New guestfish commands

+  command.
