Dealing with "Emergency Mode"
When things come ungluded on booting,the user is offered a root login,
which seems to be referred to as "Emergency Mode"
journalctl is suggested as a place to start looking for causes. In the
output there are no priority 0 and 1 (and perhaps 2) problems. Running
the reboot with display of the process (I forget exactly how I edited
the boot command) shows nothing of interest.
fedora-live runs without problems, and I'm able to reinstall 37 and
reboot it. One the next reboot - or the one after that, I'm back in
Emergency Mode.
So, as I'm about to reboot :-(, Wish me luck
