After my recent full upgrade (I have not been using this PC for about three month so I upgraded a lot) I have a weird issue that does only let me boot after a couple of forced reboots.
The first few times I boot it will freeze just before the screen normally turns off for a second before showing the login screen. After pressing the reboot button on my PC it will work eventually. Which is really odd to me.
When it fails booting, one of the last lines of the journal says
systemd: emergency.service: Executable /bin/plymouth missing, skipping: No such file or directory
Which should be the cause problem, since how I understand plymouth is responsible for bootsplash (which I turned off) and user interaction before login.
What baffles me is that after some forced reboots it will randomly work again.
A web search did not turn up anything helpful, so I am grateful for any help :)
