You should *completely* understand what they do before setting them, since it can cause unusual system problems. I don't know where you read that root has to follow permissions; it's not on the init(8) manpage. Root can _always_ override permissions (just not flags; see chflags(8)). > Q2.

The O'Reilly books on individual daemons (ie, DNS, sendmail) are helpful as well.
