Improve chroot hook to to add changing /etc/login.defs UID_MIN line in casper's 25adduser script 
(fix LP bug #1003308)

hooks/chroot should remove apport-gtk and apport in stable Baltix release or 
disable automatic appear of crash dialog in GNOME after crash of application or daemon

/var/lib/dpkg/available size is 1.5Mb, maybe use dpkg --clear-avail in hooks/chroot ?

Check which recommended and suggested packages are really needed: deborphan --nice-mode

Removing unnecessary changelog.gz and other big *.gz files in /usr/share/doc/ will free > 3Mb in CD!

/etc/brltty/zh-tw* and ko.ctb uses 2Mb, maybe simply remove these files in hooks/chroot ?

smbclient package uses 14 MB on CD (43Mb installed), but is recommended only by cups-client, maybe remove?

Remove unnecessary protobuf-compiler libprotoc7 packages in hooks/chroot (~300kb in CD)

Remove checkbox-qt +checkbox and replace Depends with Recommends in ubuntu-desktop (LP: #937189)

Maybe remove thunderbird from CD or repackage to use huge libxul.so (35Mb) and omni.ja files from firefox!

No recent files in GNOME 3.4 shell :(

See http://askubuntu.com/questions/128249/no-recent-files-in-gnome-shell-in-12-04

integrate file search into Gnome shell by installing this extension:
extensions.gnome.org/extension/62/journal/
If you also want recently opened files in the jump list of the appropriate program install this extension:
extensions.gnome.org/extension/33/jump-lists/

Maybe leave /sbin/getty instead of removing 3–6 virtual consoles at all in live session (see 25configure_init)?
