etc-update

Hauser

# find /etc -iname '._cfg????_*'

You should be able to see this command somewhere before:
"GNU info directrory is up-to date
IMPORTANT:2 config files in /etc need updating. "

To update, you should use your editor to open this ._cfg??? file the corresponding original one.  Compare and edit the ._cfg??? file and then replace the original one by copying over.  For more information on this, do:
# emerge --help config
