I just caught up on the thread. It looks like the core issue was never
actually resolved: "getent hosts localhost" still doesn't return the
expected result, right?
$ getent hosts localhost
::1 localhost localhost.localdomain localhost6
$ grep ^hosts /etc/nsswitch.conf
hosts: files dns myhostname
If you're not getting the expected result from "getent", and if your
nsswitch.conf lists "files", then glibc is somehow broken. "rpm -V
glibc" might tell you how, or it might not. Could be that glibc can't
In any case, DNS is now providing you with a result for "localhost", and
that'll work around most of the problems, but you really should take
steps to fix glibc. With something that low-level broken, I'd urge you
to build a new system from scratch, and automate the build with some
configuration management tool this time, so that the next time you need
to rebuild, you can do it quickly.
