The Linux Ship of Theseus
-
pick any distro and install it.
-
Then, without installing another distro over the top of it, slowly convert it into another distro by replacing package managers, installed packages, and configurations.
System must be usable and fully native to the new distro (all old packages replaced with new ones).
No flatpaks, avoid snaps where physically possible, native packages only.
EDIT: Some clarification on some of the clever tools brought up here:
chroot, dd, debootstrap, and partition editors that allow you to install the new system in an empty container or blanket-overwrite the old system go against the spirit of this challenge.
These are very useful and valid tools under a normal context and I strongly recommend learning them.
You can use them if you prefer, but The ship of Theseus was replaced one board at a time. We are trying to avoid dropping a new ship in the harbor and tugging the old one out.
It may however be a good idea to use them to test out the target system in a safe environment as you perform the migration back in the real root, so you have a reference to go by.
Easy: pick two similar distros, such as Ubuntu and Debian or Manjaro and Arch and go from the base to the derivative.
Medium: Same as easy but go from the derivative to the base.
Hard: Pick two disparate distros like Debian and Artix and go from one to the other.
Nightmare: Make a self-compiled distro your target.

Love the idea of the challenge, my issue would be lack of a validator tool to confirm I’d completed the challenge - any suggestions?
You use the new franken system to do an update to the new version of that distro’s flavour without bricking the system.
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.
debootstrap makes this easy, and familiarity with that process introduces chroot skills.
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
it is pretty terrifying to debootstrap over ssh. constantly checking that you’re on the correct system, and using the chrooted terminal. it’s like a high wire act. at least the first few times.
Oh I totally believe that. I can imagine how stressful that is.
I would watch a YouTube series doing this
Reminds me of MattKC, a guy on YouTube who does similar stuff. He ported the .Net framework to win95. very interesting videos, if think this challenge would be exactly his type.
Love him. His lego island port has been a pleasure to watch.
Oh he’s the Lego Island guy, I thought he sounded familiar.
Not quite the same but you might like the Linux from Nothing series, building out a Linux install from first principles.
Obviously lots of linux youtubers have done videos on linux from scratch too but the step by step nature is pretty enjoyable to watch.

I am not educated enough about this, but don’t these kind of games unnecesarrily strain all the servers that host the packages for people that really need them for download and most of these people run these servers for free in good will and faith that they will serve meaningful needs with positive impact? I am sorry for spoiling the fun, but I felt like I had to point this out.
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.
No? It’s the same amount of “strain” as doing two full OS installs of the different distros.
You are kind of right. I should have thought about that before commenting.
How is this any less meaningful than any other use case? Is downloading a distro to play video games ok? To shitpost on social media? To watch clickbait videos on youtube? Why is this in particular a bad use of resources?
Linux From Scratch rulez!
Migrate from Nix to Linux From Scratch!
To add sadism on top of masochism, tell all your friends how you did it in great detail
Reminds me of a recent post someone converted their system from Debian to OpenBSD via SSH only
Why does that sound familiar.
Did they load an OS into ram to run ssh then rebuild the machine, also some VPS that the provider was dragging their feet on remote hands.
I can’t find it now but basically something like that yeah. VPS provider only gave them SSH on linux so couldn’t run the openbsd installer any normal way either
“Medium: Same as easy but go from the derivative to the base.”
I can’t quite recall, but I think I did exactly that with Ubuntu -> Debian once upon a time. I think Ubuntu was only a year or so old though, so there wasn’t a huge amount of divergence back then. As a bonus anecdote I also attempted a semi-successful build of Gentoo on a PPC Mac around the same time (nothing before or after that has compared in its level of nightmare).

Amen!
Hell: from macOS to WSL.
But the rules say the system must be usable.
I have seen dozens of systems migrated from Gentoo to CentOS by live swapping the userspace and eventually rebooting into the new kernel. A hair raising experience to be sure.
Is that even possible? I’m already in panic when I remove a package and it’s dependencies with pacman 😅.
Sure I did replaced Thunar with Nemo, but a few things don’t work exactly how it should, like opening the download directory from Firefox (Known issue BTW) even though all mime-types are correctly set !
Even switching from Alternative -> Base distro seems like a really difficult task :/
I helped do the easy scenario at large scale in a fortune 50 several years ago after the vendor thought they could get greedy on the support contract renewal. Only required small changes to a few files and packages.
Possible? Absolutely. Pleasant? Hell, no.
I once switched from Debian i386 to amd64 in-place. That was MUCH harder than you would expect, I guess somewhere between medium and hard in your list. That server is still running that install btw, so in the end it all worked out.
.
I had forgotten about doing that myself. I did that on a couple servers once the distros had full 64 bit builds. Does that technically count as an architecture swap in-place as well?
New Game+: speedrun it
I’ve got a blank macbook air at home waiting for a project.
I’ve never undergone a project like this without cheating by using bedrock linux as an intermediary then “Unbedrocking” my install (officially impossible, unofficially insane) with another PM as my default to convert from debian to arch years ago.
This is gonna be fun, or hellish, idk I’ll find out.
It is quite easy to go slackware -> gentoo from what I remember but minimalist distros might be cheating
