Hi,

how should a user run journalctl, when logging in doesn't work? From a
live media it would be possible to mount the install and to e.g. run

  sudo systemd-nspawn -qD /mount/point

and after that to run

  journalctl

but even this might fail, so after mounting at best

  sudo strings /mount/point/var/log/journal/*/system.journal

might provide some information. However, even

  less /mount/point/var/log/boot.log

or any other log IMO is more confusing, than helpful as the first step
of troubleshooting.

IMO the first step of troubleshooting should be to read if GRUB and/or
the startup messages are complaining about something. Users who prefer
an idiotic splash thingy over messages, simply need to push the Esc-key
to see the startup messages.

Are there any GRUB (or what ever bootloader you are using) messages?
If not and assuming it should start booting, are there any messages
after pushing the Esc-key?

Regards,
Ralf
