su - What does this mean?

[Javasnob]

Whenever I su to root, I get the following output:

rob@TheRing:~$ su
Password: 
configuration error - unknown item 'FAILLOG_ENAB' (notify administrator)
configuration error - unknown item 'LASTLOG_ENAB' (notify administrator)
configuration error - unknown item 'MOTD_FILE' (notify administrator)
configuration error - unknown item 'FTMP_FILE' (notify administrator)
configuration error - unknown item 'ENV_ROOTPATH' (notify administrator)
configuration error - unknown item 'PASS_MIN_LEN' (notify administrator)
configuration error - unknown item 'CHFN_AUTH' (notify administrator)
TheRing rob #

What does this mean and how do I fix this? It scares me a little...

Thanks!

This happens sometimes in gentoo when you update your install, for example with "emerge -uD world, without then updateing the config files. Run etc-update, and you'll have a list of config files that need updateing, you can do it all automaticall, NOT ADVISED, or do them manually and see each of the changes...

Post back if this has not fixed your problem, but I've only ever encountered this, and I have a few times, under the rubric of an extremely large emerge -uD world...
