switch and a set of flags. Get rid of DEFAULT flags entirely. Print
warnings if on/off switches are not set, or are set incorrectly.
Add a shell function to simplify this on/off switch testing.
- add missing update_motd and ntpdate_hosts variables
- fix incorrect variable names (syslogd_flags and kerberos_server)
- xntpd(8) has been integrated
- kerberos_server is no longer used by rc.local
- add some xrefs
plus some misc. cleanup.
