For the records, a number of dangling symlinks were left over, too: # find /etc/systemd/ -xdev -xtype l | grep grub /etc/systemd/system/multi-user.target.wants/grub-common.service /etc/systemd/system/hibernate.target.wants/grub-common.service /etc/systemd/system/suspend.target.wants/grub-common.service /etc/systemd/system/hybrid-sleep.target.wants/grub-common.service /etc/systemd/system/suspend-then-hibernate.target.wants/grub-common.service
Guess the service wasn't disabled before it was removed?
