Yes, those 90 sec waiting for nothing is one of the most annoying
"features" of systemd that I would love to get rid of. And most annoying
aspect of it is that problem is rarely constant. It can exist in one
release in systemd, vanish in other, and then come back again in next
release. And it can occur once in every 10 shutdowns/reboots, or not
occur once in every 10 shutdowns/reboots.
