So I hardcode the keys in my %post and compare them to what was installed, instead of blindly importing them

…snip
# import the pgp key
cmp /etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6 - <<GUGU
-----BEGIN PGP PUBLIC KEY BLOCK-----
shiny KEY GOES HERE
-----END PGP PUBLIC KEY BLOCK-----
GUGU

if [ $? == 0 ]; then
   rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6
fi
snap...

still not quite sure what to do if the key does not match in the previous comparison.
however, here are the keys I know of and if someone keys does not match she might raise her hands.

(what is the RPM-GPG-KEY-CentOS-Security-6 key for?)
