main: Warn about unexpected configuration location

When using the `--fork` flag, and no user or config arguments are
supplied, the configuration folder will end up with whatever the default
`daemon` user has set, which is often `/sbin` set as the homedir.

This is weird, but not 'wrong' per say. Lets warn the user that forking
can have an unexpected side effect.
