Some people like to spring clean, rearrange their house, wash their car, build shelves, or some other chore.

Me? I just spent a couple or so days manually "syncing" the packages on my 2 laptops. That is, making sure that `apt-mark showmanual` and `dpkg-query -l` shows the exact same output on both of them, by manually apt-marking / apt-get installing / removing the exact same set of packages as manual/auto and ensuring the exact same set of "recommended" / "suggested" packages are pulled as dependencies on both.

The end result is a sysad's ideal - I have wasted countless hours making sure absolutely nothing has changed. But hey, my package list is clean, and if aliens from a software dimension abducted one laptop... I have an exact clone ready.
