 Posted: Thu Feb 16, 2006 6:20 am Post subject: run script before swapon how? |
 |
|
Hi,
I need to run
/etc/init.d/dumputils start
before my swap is turned on. I entered that exactly right before swapon in /sbin/rc. For some reason it appears that it's not running at all. This is a script that configures and starts the lkcd utility for kernel debugging. I just want to know how I can get it running before swapon? Can I just add it to a runlevel? Which one?
Alternatively I could disable swapon and do all this manually. But I'm not convinced it's being run from there. |

As far as I can see while booting the '/etc/init.d/localmount' script takes care of swapon. So you can add your initscript to the previous one's 'depend' list. Or just simply edit the 'localmount' script and add your prefered lines before the line.

How about putting: | Code: | depend() {
before localmount
} |
in your dumputils script

I saw that /sbin/rc was in inittab under start scripts or something like that. So I thought that was my best bet. Do I need to then add dumputils to a runlevel? I'm wondering how gentoo knows to run that script before local mount. Does it read through all the depend functions before running any scripts? Or is this checked when you rc-update? |

I added dumputils to boot with rc-update after adding the dependency mentioned before. I see the usage message displayed 3 times at startup. But it was never actually run. The usage script looks like
dumputils {start|stop|reload|force-reload|restart}
Was there something else? |

Ok, I got it. I had to rewrite it using functions and remove the case statement and exit commands.
I can see it running at startup now. But I'm not convinced it's happening at the correct time. It appears to be happening right before the ethernet interface is brought up, which is in the default run level. So unless localmount has no output, something must be wrong. Is there anyway I can verify the script load order? 'rc-update show' shows dumputils in boot.
thanks |

It seems that swapon is called at sometime before localmount, possibly from /sbin/rc (as you noted),
together vith udev pts and such.
You will probably need to take the functional part (ie. the start function's content) and add it to /sbin/rc
or maybe call the script with the argument "start" from there.

The swapon command is in rc (under runlevel sysinit I think), but as far as I can tell, that code is never executed. No matter what I put there, it isn't getting executed. I tried the scripy and copy/pasting the commands right in there. It must be getting turned on somewhere else.
Thanks for your help. I might give up on this. It's no longer critical to get this script running. |

| I was able to verify the order using log files. Despite depend, localmount is running first. And that's where swapon is being run. |

Hello,
I pop in to say that even /etc/init.d/test | Code: | #!/sbin/runscript
depend() {
before bootmisc
}
start() {
einfo "Hum... I am late"
ewarn "The before thing does not work that well in the boot runlevel!"
} |
rc-update add test boot And that is also true with before localmount and others, even hdparm that is not home-made (synss-made) does not start before bootmisc as depend() suggests... That's a bug right?
As such, test is the last script executed at the boot runlevel (on x86, with everything up-to-date, but that's a while I noticed that)
[EDIT] The issue is known and addressed in sys-apps/baselayout-1.12* now in the ~x86 branch.

Hi,
i got that kind of problem too.
I need to load an init script before the localmount init script starts. I've read the gentoo init script guide an played with the depend / before / need stuff in the init scripts. but without success.
The depend part of my initscript (called dasd_init):
| Code: | depend() {
before localmount
after modules
}
|
... and from localmount
| Code: | depend() {
after checkfs dasd_init
} |
Why is localmount still starting before dasd_init?
