Ubuntu todo

• new tidy
• wikidiff2
• FSS
• /etc/sudoers
• /etc/ntp.conf is wrong, uses zwinger instead of multicast client. See /home/config/others/etc/ntp.conf for a suitable configuration file

We can defer these by using the fedora scaling cluster for now:

• ImageMagick is 6.2.4 Q16, should be 6.2.8+, Q8
• librsvg is stock, needs security patches. See /h/w/src/packages/install-librsvg
• Font consistency:
  • We have DejaVu fonts 2.14, needs to be upgraded. Debian unstable has 2.19, we could upgrade to that and also upgrade the FC package, for consistency.
  • Lots of fonts missing, e.g. Japanese miscellaneous fonts. We probably would benefit from just installing all ~120 font packages
