it's the general SYSV way to run scripts sequentially, not HP-UX ones.

on a client machine, right. but on a server running some sort of databases...

well, too much informations, kills informations. I'd like the way HP-UX
goes. just a summary and if an error occur, look at /var/adm/rc.log
for error messages. I've even implemented this under FreeBSD :)

at work, I run SYSV based OSes (HP-UX, Solaris, IRIX). from my point of view,
the bests startup scripts are HP-UX ones located in /etc^H^H^Hsbin/init.d
and configuration files located in /etc/rc.config.d. I'd like the idea to
stop/restart a service just by doing /sbin/init.d/nis.server stop/start.
I although like the way to number them in /etc/rc?.d, so they start in the
order you want. just like BSD /etc/rc files. but if you need to restart
some services, you don't have to egrep it in /etc/rc* to find the right
command and arguments like I need to do under BSD systems.
it's a pain to do something like ps -ef|awk '/yp/&&!/awk/{print $1}|xargs kill
if a process is missing, just do /sbin/init.d/nis.server start and it restart
the missing process. no need to stop all of them to have the right way like
needed under Solaris. yes, under HP-UX, a service isn't started if it's already
running.
PS : of course, I'm talking about HP-UX 10.x, not HP-UX 9.x which make uses
of /etc/rc files like BSD does :)
