Ok wow! This is really impressive. I couldn't even run Windows or Debian or something like that for 15 years, yet you managed to do it with Arch. May I ask what was the main reason behind trying to keep this Arch installation for so long? Were you just to lazy to reinstall or are there other factors?
My arch install is from 2015. It just works, why should I reinstall?
@partizan@lemm.ee mentioned cloning the drive and moving it to another computer. I imagine reinstalling would be easier at that point, that's why I asked.
Well not really, cloning is much easier than reinstalling and then configuring everything again...
I have LVM set up from the start, so usually I just copy the /boot partition to the new disk, and the rest is in a LVM volume group, so I just use pvmove from old disk to the new one, fix the bootloader and fstab UUIDs, and Im ready to reboot from new disk, while I didnt even left my running system, no live USB needed or anything. (Of course I messed it up a first few times, so had to fix from a live OS).
But once you know all the quirks, I can be up and ready on a new drive withing 20mins (depends mainly on the pvmove), with all the stuff preserved and set
That's really cool, how can I learn more about LVM and that kinda stuff?
There is many tutorials and how tos, this is quite nice one:

BTW some filesystems like btrfs and ZFS already have a similar functionality built in...
Thanks :)
