I did a
yum reinstall \*
  .
gdm or something still hangs.
The gdm log suggests it is happy.

Thank you, but my concern is not specific to X.
X I can easily get from install options.
I have repositories that are not listed in the install options.
My recollection is that there is more to it than restoring a yum directory.
There is a bunch of Berkely DB stuff under /var/lib/rpm .
Would restoring /etc/yum.repos.d and /var/lib/rpm/Pubkeys be sufficient
to activate all the repos from my old install?
