Question regarding /etc/inittab

Hello all.
I have a fairly basic HP-UX start up question that I'd like to confirm with the experts out there.

After the init process is started it reads the /etc/inittab configuration file from top to bottom, correct?

Assuming this is correct, would the /sbin/rc script (and all scripts in sequencer directories /sbin/rc0.d, /sbin/rc1.d, /sbin/rc2.d...) be executed before the "h1" entry if my /etc/inittab file contained the following:

sqnc::wait:/sbin/rc /dev/console 2>&1 # system init
#powf::powerwait:/sbin/powerfail >/dev/console 2>&1 # powerfail
cons:123456:respawn:/usr/sbin/getty console console # system console
#ttp1:234:respawn:/usr/sbin/getty -h tty0p1 9600
#ttp2:234:respawn:/usr/sbin/getty -h tty0p2 9600
#ttp3:234:respawn:/usr/sbin/getty -h tty0p3 9600
#ttp4:234:respawn:/usr/sbin/getty -h tty0p4 9600
#ttp5:234:respawn:/usr/sbin/getty -h tty0p5 9600
krsd:123456:respawn:/sbin/krsd -i
sfd:123456:respawn:/sbin/sfd
#ups::respawn:rtprio 0 /usr/lbin/ups_mond -f /etc/ups_conf
#samd:23456:respawn:/usr/sam/lbin/samd # system mgmt daemon
cim1:3456:respawn:/opt/wbem/sbin/cimserverd
h1:3:respawn:/sbin/init.d/init.cssd run >/dev/null 2>&1

The way I understand it, init would start /sbin/rc and wait for it to complete before proceeding to the next entry in /etc/inittab.

I'm just looking for some clarification on whether an entry such as /sbin/rc3.d/S990oracle would be kicked off before the "h1" entry from the above sample /etc/inittab file.

I hope this question makes sense.

Any feedback is welcomed.

Thank you.

Tom Wolf

Tom,

The rc sequence runs to completion before the next inittab line is processed. So you should be safe with your cssd startup.

I actually verified with a freshly rebooted system and you can do the same.

I checked the /etc/rc.log and the startup time was 9:17:56 and the completion time was 9:19:17.

Then I used "ps -ef |more" and checked the STIME (start up time) for samd and krsd and both were 9:19:17.

This clearly shows that the subsequent statements in inittab are executed after the rc sequence is completed.
