After completing the challenge and making sure your system is usable and can survive a reboot:

If you’ve kept the old package manager, search for installed packages and make sure that the package manager itself is the only thing left. Then delete it.

The beauty of this exercise is you can make it as easy or challenging as you want just by changing the targets, and finding different combinations can keep things interesting.

As other commenters have said, its about as strenuous as doing two normal installs.

However, if you want to do this challenge but feel guilty about the consumed resources, consider donating to the two distros you are performing this with to cover any additional service costs. In all likelihood it’ll only cost them fractions of pennies, but any reason to donate to FOSS is always appreciated.

Oh I totally believe that. I can imagine how stressful that is.

This goes against the spirit of the challenge, but as its a singleplayer game (unless you bring friends and SSH!) you can definitely choose to allow dd, chroot, and similar tools

I wasn’t sure if Hector was gonna quit vtubing too after the Rust thing. Kind of a delayed response as his alter ego but it makes sense.
