I still don't understand under which conditions this happens, because it does work sometimes, under specific conditions

[dalto8]

This is potentially due to a change in Calamares 3.3 where swap is now activated automatically as part of the mount module.

I got it working via a very very dirty fix : a well-timed sudo swapoff /dev/nvme0n1p3 (~2 seconds time frame) in-between the two swapons

I used to think game devs were just getting lazy, but it turns out the quick time events were actually just training for installing NixOS.

Unfortunately this worked for me
