The Linux Ship of Theseus

Crossposted from: https://lemmy.ml/post/27387345

  1. pick any distro and install it.
  2. 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.

Difficulties:

  • 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.

Clarifications

  • 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.

My main system was installed as RedHat 4.2 over quarter of a century ago. At some point I migrated it to rawhide one package at a time. Then some years later I installed portage and started building gentoo packages until eventually my system was fully converted to gentoo. The hardware was fully replaced a few times over as well. Sometime one component at a time, sometime wholesale. The system is still chugging along just fine.
