Hi all,
One of my F9 systems experienced a utility power failure, and now
non-root users can't log in. Googling based on the errors suggests that
some critical library file has probably become corrupted. Could be
anything, really.
In cases like this I usually do
rpm -qa | xargs yumdownloader
rpm -Uvh --force *.rpm
to re-install every single rpm. In theory, it should end up pretty much
in the same state. It's worked well before, anyway.
Is this the slickest method to rescue a limping system? Are there less
hacky methods? I could re-install from cd/dvd or a revisor iso, but that
seems to increase the odds of clicking the wrong button and overwriting
my data...
Tips welcome!
- Mike
