If you want to _fix_ it, then I would suggest updating swapctl(8) so that it's -A option, instead of totally skipping selected swap partitions which are already mounted, instead updates the priority of them if they don't match what's in the fstab.

If that's correct, then there's no supported way to change it: the addition of the swap partition from the boot disk is done by the kernel before starting init, in swapmount(), which hardcodes a priority of zero.

Hello, I tried on amd64 6.3 and on amd64 -current and I have not been able to reproduce the issue. What is the result if you remove your 2 swaps with # swapctl -d e7f9094bf357d407.b # swapctl -d 2e04cb867188f137.b and that you type # swapctl -A after this, you should see the priorities correctly assigned after typing "swapctl". Hello, I performed what you just suggested : Tried to remove the two swaps : OK none remaining Tried to reload the fstab : OK got priorities 0 and 1 Performed "halt -p" : OK computer dead like a stone Power on... Check swapctl : two swaps present with both priority at 0. There's something i do not master within the boot process. Note : this host has been freshly reinstalled with wiped out SSD. Eric.
