Hello everybody! here's the problem:
In my EndeavourOS laptop I had a /swapfile, but couldn't take snapshots with snapper because of it (if I understood correctly). So, I created a 16Gb swap partition using GParted from a live USB. Then, I edited /etc/fstab to remove the line about the swapfile and to add the newly created swap partition:
if I run sudo swapon -a it gets enabled correctly and it all works fine. The problem however is that when I reboot the machine, it gets stuck in the systemd screen saying "a job is running for /dev/disk/etc..." forever, and the only way I have to log in is to boot from a live USB, modify /efi/loader/entries/somethingverylong.conf to add these kernel options:
systemd.swap=0 noresume
and then reboot, and manually enable the swap.
I'm not understanding very well what's happening here. why is the system stuck if I don't add these parameters? how can I solve it?
