Botched 7->8 upgrade, thoughts how to recover?

[Tuc]

Hi,

Figured this might be a bit more than -questions worthy...

I was following some instructions online about upgrading 7 to 8... 
And... Well... Something went horribly wrong during "make installworld". 
I lost my ssh session (Mistake 1 - Console dummy!) and now in multiuser 
I can't log in. I logged in single user and commands are iffy about 
working. "ls" is fine, but "ls -l" coredumps. I tried to redo the 
installworld, but it seems to get somewhere in libc man pages and then 
quits. Could be that "ln" is screwed.

Any thoughts on how to recover? I did an rsync of the system elsewhere 
beforehand, so if it works I probably could just get it all back that 
way. I was HOPING to go forward to 8. Is there some way I can do the 
equiv of a "make installworld&&make installkernel" off some media so I 
don't overwrite config, password, group, etc.

Thanks, Tuc
