[Linux-users] linux update(s)

[Jon Hart]

sudo on darkside has been upgraded to the latest version to protect us from
a vulnerability in our postfix + sudo installs.  Additionally, the at
package has been upgraded.

Fwiw, all this was done sometime early last week, but I never sent email.
The linux machines that are currently deployed had their sudos chmod'd
accordingly until we can push out the new image.

Next on deck is possibly syncing our SSH clients and daemons.
