gitlab-runsvdir not starting after upgrading to 11.2

reconfigure fails at ruby_block[supervise_redis_sleep] action run after upgrading to 11.2 (from rc6).

don't know what happended, previous upgrades worked fine for the last two years!

sudo systemctl restart gitlab-runsvdir does not work at all (no response)

Workaround

sudo systemctl disable gitlab-runsvdir
sudo systemctl enable gitlab-runsvdir

Workaround 2

If systemctl list-jobs shows plymouth-quit-wait.service to be running preventing the system to enter multi-user.target try uninstalling plymouth to see if it helps!
