Re: [PLUG] Editing System V init
|
be careful, doing that will make both /etc/rcS.d/_S51ntpdate and /etc/rcS.d/S51ntpdate execute and I don't think thats what you want. I would move /etc/rcS.d/_S51ntpdate to another location.

By default, my distro tries to run an ntp update script before it
initializes ppp. The documentation on the distro web site shows you how
to disable the ntp init script, but I don't want to do that. I want to
edit the startup so that it runs _after_ ppp is initialized.
I installed the webmin init module, but need to read about the runlevel
and 'start at' and 'stop at' settings before I make any changes. Google
hasn't helped me find documentation. Can anyone recommend a place?
The way it works, roughly (and totally solution dependant, but most
linux distros do it this way these days) is that the kernel boots, and
at some point hands thing off to init. init runs all of the scripts
that start with S in the rcS.d directory, and then switches to the
'default' run level - what that default is is completely distribution
dependant, although I think Redhat-alikes all use 5.
Then init runs all scripts in rc5.d directory that begin with an S with
the start argument (and really, it should also run all scripts that begin
with a K with the stop argument, but many don't). The only real things
to know about the hacked SysV init that most linux distros use is that
a) scripts whose names start with S should get run with the start
argument
b) scripts whose names start with K should get run with the stop
argument
c) All scripts in a directory are run in numerical order
d) At boot, S is first, then default run level.
That's the basics for managing it.
That is what is complicated. The ntpdate script in in rcS.d and the ppp
script is in rc2d through rc5.d. I fear putting ppp in rcS.d is a bit
too radical and may lead to unintended consequences.
BTW, I am running Kubuntu 5.04 (hoary) which is Debian based. The only
documentation it points to is chapter 9 of the Debian Policy Manual.
Ah, I see the problem. You are using pppoe or something, and pppd
starts too late for ntpdate, so boot up takes forever.
So, the simple answer is
mv /etc/rcS.d/S51ntpdate /etc/rc2.d/S51ntpdate
OK. Worked. First I did
cp /etc/rcS.d/S51ntpdate /etc/rcS.d/_S51ntpdate
then
mv /etc/rcS.d/S51ntpdate /etc/rc2.d/S51ntpdate
as I read that init will only execute scripts that start with S or K, and this would make it easier to restore the system if what I did caused problems.
After the changes I rebooted and it worked fine. Thanks for all of your help.
