(Just saw sticky about bash bug. Will try re-install, and get back here)
After doing an update (for F16) things went from bad to worse.
The new kernel didn't get installed properly, since grubby failed to run. But that was caused by (g)awk not being found. While tracing that problem down, I found:
/usr/bin/gawk -> ../../bin/gawk
/bin/gawk -> ../usr/bin/gawk
This also creates a problem for booting with a previous kernel as well, since it needs to run awk.
So, like, where is the real gawk?
I tried to reinstall gawk (via yum). But even if I deleted both symlinks, the reinstall just puts them both back.
FWIW: Looking at an F17 installation, I see that a real gawk is in both directories (no links). In an old F14 installation there is a real gawk in /bin, and a symlink to that in /usr/bin.
Any suggestions on how to correct this?
