Description of problem:
I tried adding a serial console to my RH9 box.  Part of this involved adding the
following line to /etc/inittab:

S0:12345:respawn:/sbin/mingetty ttyS0

The for loop on line 38 of /etc/rc.d/rc.sysinit is driven by a grep piped to a sed:

grep '^[0-9]*.*respawn:/sbin/mingetty' /etc/inittab | sed 's/^.* \
tty\([0-9][0-9]*\).*/\1/g'

It looks like the grep part is trying to pull out all the respawning mingetty
lines dealing with standard (non-serial) TTYs.  Unfortunately, the regex given
to grep doesn't quite work this way.  The above grep pulls out the S0 line too
and the piped-to sed starts outputs the following for the for-loop to iterate over:

1
2
3
4
5
6
S0:12345:respawn:/sbin/mingetty ttyS0

The pattern "^[0-9]*.*respawn:/sbin/mingetty" is as good as
"respawn:/sbin/mingetty" since the first "*" means there can be zero or more
digits at the beginning of the line.  I believe that intended pattern should be:

"^[0-9]\+.*respawn:/sbin/mingetty"

This will pull out ensure that all lines extracted will begin with at lest one
digit.
