freeBSD single user mode disaster mergemaster build makewerld
i was trying to do cvsup for the first time.. i closed out this question:
https://www.experts-exchange.com/questions/22470294/freeBSD-makebuildworld-failed-now-what.html
because we made significant progress, and it is long long long now.
i made a new question:
https://www.experts-exchange.com/questions/22470294/freeBSD-makebuildworld-failed-now-what.html
but now i am having a serious disaster. i can no longer log onto the system. when
i did mergemaster -p it was like being in the vi editor for the first time (for me that was about
22 years ago in milwaukee on evax) i had no idea what was happening there were
all these questions i don't remember i must have deleted /etc/passwd or something.
i don't know what to do now {:(

i moved three files..
i can't log on, but i can run in single user mode. does that qualify as a "running system" should i start
over from step 1 and do it all in single user mode? maybe i better not try until hearing from somebody.
here is what is happening on freebsd-stable mailing list:

and it blew up in my face

okay now i have a browser and a broken set of terminals. i guess i am going to have to go back
over my old questions on how to make my prompt werk. i will make a new question if i have problems
i guess. also.. i have no idea if i have properly built werld that mergemaster -p thing caused this
mess.

Try
uname -a
If it's giving you version 6.2, things should have been upgraded properly

/var/tmp/etc
Boot in single user mode, do a

This should enable you to login again. There is a but...
There might have been changes made during the buildworld process, obviously, those are missing in the backup file. Make sure all your programs are running as expected...
