I'll keep this offline for a moment. There is a RedHat krb5-libs-1.2.7-14 rpm that has libcom_err.so.3 in it
If it is installed with the --oldpackage option
and a link is made in /lib to /usr/kerberos/lib/libcom_err.so.3.0,
is this going to break anything?
Yes. Any application compiled for Fedora with the standard kerberos installation will be linked to libcom_err.so.2. Installing the old kerberos lib will add it do your loader path, and you'll end up with unreliable loading / symbol resolution. Fedora applications will load libcom_err.so.2, and the old kerberos libs, and because of those will load libcom_err.so.3. As a result, Fedora applications may crash at random.
Is it really that hard to get the src.rpm for your application and: rpmbuild --rebuild <src.rpm>
