Redhat 5.2 system daemons (e.g. sendmail, etc.) cannot
be aborted/skipped by hitting Ctrl-C while they are starting
up like you can on FreeBSD.
Background: Several system daemons in addition to sendmail
hang for several minutes when DNS is not properly configured
(for example, in the process of setting up a new Redhat
box), so without being able to skip these daemons on
startup, the user has to wait 10-15 minutes before the
machine is usable again, or perform an unsafe boot ("hit
the reset button") and risk file system corruption.
You ought to be able to hit Ctrl-C on the console to
terminate these processes and continue boot-up without
having to wait 1/4 hour to get to the prompt.
Thank you for the suggestion. It has been noted and will be considered
for future Red Hat releases.
