3 # Check what packages are needed to get upgraded on all machines
5 # Depends heavily on having ssh key authentication set up to all
6 # boxes. That's why I run it on my own workstation.
8 # Regular debian upgrades are detected by running
10 # on every machine, and parsing the output.
12 # We have decided to maintain some packages manually on some
13 # machines, so that system-level upgrades will not disturb
14 # applications, which may need more hand-holding. These are
15 # extracted from our apt repository, and queried on every
16 # server with apt-cache policy. This way, as soon as a package
17 # is released on our repo, it will get listed here.

24 # and architectures at the same time. Gets only the highest version from
25 # all, and reports anything less than this. Good enough for now.

28 # and display next to the packages, so we can see how long they have
29 # been lingering. Boldface them if older than some limit
