 grml-live-addons - templates/boot/addons for grml-live
Changes: 
 grml-live (0.9.17) unstable; urgency=low
 .
   [ Frank Terbeck ]
   * grml-live-remaster: Support $VISUAL and fall back to 'vi' if
     EDITOR is empty. [Closes: issue664]
 .
   [ Michael Prokop ]
   * Mention speakup.synth=... and hwspeak in grml-cheatcodes.txt.
   * 15-initsetup: warn if /etc/runlevel.conf (and therefore live-rc)
     does not exist and skip rest of the script then.
   * Software related changes:
     - Drop package snort from GRML_FULL and all the workarounds for it.
       It's once again uninstallable in Debian/unstable.
     - Drop package sing from GRML_FULL (removed from Debian, see #530487).
     - Drop package nemesis from GRML_FULL (unmaintained upstream and
       uninstallable in Debian, see #423201 and #529508).
     - Drop package paketto from GRML_FULL (removed from Debian, see #530486).
     - Drop package ifupdown-scripts-zg2 from GRML_FULL.
   * Set APT_LISTCHANGES_FRONTEND and APT_LISTBUGS_FRONTEND to 'none'
     on upgrade actions in /etc/grml/fai/config/hooks/instsoft.GRMLBASE.
   * Update /boot/grub/* files in build output on every invocation of
     grml-live (as we do it for isolinux stuff too), so the variables
     inside menu.cfg are up2date if rebuilding the ISO. [Testing: issue676]
   * Use variable for $FLAVOUR.squashfs in grub's menu.lst as well.

Thanks for the fix, Frank! Applied and pushed.

thx && regards,
-mika-

The grml-live-remaster script does not support $VISUAL, and it does
not provide a fallback if $EDITOR is empty or unset.

Attached patch cures that.
Again, I can just push that out if the patch is okay.

Regards, Frank
