Even with around 15000 PassMark CPU Points the race to the mounting of /tmp is unreliable. I switched to a memory based /tmp. I removed the mentioned lines from /etc/crypttab and /etc/fstab and added tmpfs /tmp tmpfs mode=1777,strictatime,nosuid,nodev,size=4G

One or two restart are required to fix this problem. ############### Independent of the success of the boot process, the log message related to the problem seem to be: Aug 17 07:11:02 hostname systemd[1]: cryptsetup.target: Found ordering cycle on systemd-cryptsetup@vol\x2dtmp_crypt.service/start Aug 17 07:11:02 hostname systemd[1]: cryptsetup.target: Found dependency on systemd-random-seed.service/start Aug 17 07:11:02 hostname systemd[1]: cryptsetup.target: Found dependency on zfs-mount.service/start Aug 17 07:11:02 hostname systemd[1]: cryptsetup.target: Found dependency on zfs-import.target/start Aug 17 07:11:02 hostname systemd[1]: cryptsetup.target: Found dependency on zfs-import-cache.service/start Aug 17 07:11:02 hostname systemd[1]: cryptsetup.target: Found dependency on cryptsetup.target/start Aug 17 07:11:02 hostname systemd[1]: cryptsetup.target: Job systemd-cryptsetup@vol\x2dtmp_crypt.service/start deleted to break ordering cyc> Aug 17 07:11:02 hostname systemd[1]: Unnecessary job for /dev/mapper/vol-tmp was removed.
