If you are using LVM - check LVM. If you keep the disk in the machine - remove the swap partition. Repeat the test. # find /lib/systemd/ | grep swap /lib/systemd/system/swap.target also # grep -i swap -r /lib/systemd/ Binary file /lib/systemd/systemd-udevd matches /lib/systemd/system/sysinit.target:Wants=local-fs.target swap.target /lib/systemd/system/sysinit.target:After=local-fs.target swap.target emergency.service emergency.target /lib/systemd/system/swap.target:Description=Swap /lib/systemd/system/systemd-journald-dev-log.socket:# Mount and swap units need this. If this socket unit is removed by an /lib/systemd/system/systemd-journald-dev-log.socket:# isolate request the mount and swap units would be removed too, /lib/systemd/system/systemd-journald.socket:# Mount and swap units need this. If this socket unit is removed by an /lib/systemd/system/systemd-journald.socket:# isolate request the mount and swap units would be removed too,
