extra details about the guest itself in order to get to its
UID->username map (eg. /etc/passwd from the guest).
-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.
- - then implement write-file properly
-
febootstrap / debootstrap inside appliance
------------------------------------------
Complete the Haskell bindings (see discussion on haskell-cafe).
+PHP bindings
+------------
+
+Add bindtests to PHP bindings.
+
Complete bind tests
-------------------
Should we bother having the daemon at all and just link the guestfsd
code directly into libguestfs?
-Supermin appliance to febootstrap
----------------------------------
-
-Supermin appliance functionality should be moved into febootstrap.
-
Ideas for extra commands
------------------------
findfs
logsave
mklost+found
+ ext2undelete
SELinux:
chcat
Useful imaging tool:
http://man.linux-ntfs.org/ntfsclone.8.html
-Standard images
----------------
-
-Equip guestfish with some standard images that it can load
-quickly, eg:
-
- load ext2
-
-Maybe it's better to create these on the fly?
-
virt-rescue pty
---------------
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.
+
+Is it even possible?
+
+Integration with host intrusion systems
+---------------------------------------
+
+Perfect way to monitor VMs from outside the VM. Look for file
+hashes, log events, login/logout etc.

+-N option should be generated
+-----------------------------
+
+'-N' option should generate documentation in guestfish(1) manpage.

+Fix 'file'

+
+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
+to avoid having to carry huge images.
+
+Update: I managed to fit a real-but-minimal Fedora 13 image into 6.2 MB.
+See: http://rwmj.wordpress.com/2010/09/07/tip-pack-files-into-a-new-disk-image/#content

+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
+----------------------
+
+'list-filesystems' => list mountable filesystems
+
+We could implement this as a new API call, replacing a number of areas
+of the current code where this is done already (in virt-inspector and
+elsewhere). What we normally do to find out if a partition contains a
+mountable filesystem is to just blindly mount it, and see if that
+succeeds. However the kernel won't let us do this if the filesystem
+is already mounted somewhere, so a naive implementation of this in the
+daemon won't work. We would have to check if the partition was
+already mounted.
+
+Could we make guestfish interactive if commands are used without params?
+------------------------------------------------------------------------
+
+><fs> sparse
+[[Prints man page]]
+Image name? disk.img
+Size of image? 10M
+
+Common problems
+---------------
+
+How can we solve these common user problems?
+
+[space for common problems here]
+
+Better support for encrypted devices
+------------------------------------
+
+Currently LUKS support only works if the device contains volume
+groups. If it contains, eg., partitions, you cannot access them.
+We would like to add:
+
+ - An easier way to use this from guestfish.
+ - Direct access to the /dev/mapper device (eg. if it contains
+ anything apart from VGs).
+
+Display image as PS
+-------------------
+
+Display the structure of an image file as a PS.
+
+Greater use of blkid / libblkid
+-------------------------------
+
+guestfs_zero should use wipefs. See wipefs(8).
+
+There are various useful functions in libblkid for listing partitions,
+devices etc which we are essentially duplicating in the daemon. It
+would make more sense to just use libblkid for this.
+
+There are some places where we call out to the 'blkid' program. This
+might be replaced by direct use of the library (if this is easier).
+
+Remove repo from appliance name
+-------------------------------
+
+There's no need to have the appliance name contain the repository name
+(ie initramfs.x86_64.img instead of initramfs.fedora-13.x86_64.img).
+
+Visualization
+-------------
+
+Eric Sandeen pointed out the blktrace tool which is a better way of
+capturing traces than using patched qemu (see
+contrib/visualize-alignment). We would still use the same
+visualization tools in conjunction with blktrace traces.
+
+Virt-df UUID
+------------
+
+Virt-df and any other tools with --csv output should be able to print
+UUID of domain. This allows you to track the real domain across
+renames etc.
+
+Add-domain command
+------------------
+
+guestfs_add_domain (g, "libvirt-dom");
+
+However this would need to not depend on libvirt, eg. loading it
+on demand.
