rc.conf DAEMONS '@' question

archuser · 2006-10-01 12:36:03

In rc.conf it says to put a @ infront of a daemon to load it in the background.

What exactly does this mean and which daemons should I consider loading up in the background?

Cheers.

detto · 2006-10-01 12:43:07

Mh, now as you mention it ...
Am curious now too, maybe some could speed up boot process a bit when backgrounding ? Well boot is fast enough anyway, but this options must have a reason to exist

cheers,

It means the next daemon listed will start without waiting for the prefixed daemon to finish.. uh, e.g my daemons line:

DAEMONS=(syslog-ng network dbus hal portmap @fam @shorewall @samba @netfs @crond @alsa @mpd)

Basically, shorewall will start before fam has finished loading, and so on. You have to use a little common sense to figure out what needs to be running before other things can - like portmap must be running before fam I believe. I'm not sure my setup is optimal, I could perhaps background one or two more, but i'm not all that concerned right now.

Anyway it's worth playing with and this setup saves me maybe 10-20 secs in boot time at a guess.

archuser · 2006-10-01 13:11:46

Ah, ok. So when ntp takes forever to synchronise with the server I can just add '@' to it and load the other things without waiting for it to finish.

So what your saying is the @shorewall will start without waiting for @fam to finish, but @fam still has to wait for portmap because portmap is not prefixed with the '@'?

Kindred · 2006-10-01 13:14:23

Yes, exactly.

elasticdog · 2006-10-01 14:58:27

DAEMONS=(syslog-ng network netfs @sshd @crond @ntpd @alsa)

Mine, for reference...

archuser · 2006-10-01 18:14:07

Cool. This is what mine now looks like.

DAEMONS=(syslog-ng network dbus hal portmap @fam @firestarter @ntpdate @netfs @crond alsa)

Any advice on how to improve it would be cool.

You can background alsa.

karsten · 2006-10-01 22:45:50

i think you can background dbus and/or hal i don't remember.

slubman · 2006-10-02 08:00:50

hal automatically start dbus.

This is one the first line in /etc/rc.d/hal

       #Check for running dbus, start when not running
        ck_daemon dbus && /etc/rc.d/dbus start

So you can delete dbus of your DAEMONS

archuser · 2006-10-02 17:52:55

Cheers guys. I've deleted dbus and backgrounded alsa. My system startup is tons better now.

detto · 2006-10-02 18:18:33

Here's mine now for reference:

DAEMONS=(syslog-ng network @hal @fam @samba @avahi-daemon @alsa gdm)

It works, i guess. But am not sure.
Where can i see which daemons got started / are running :?:

Kermit · 2006-10-02 18:48:35

@detto -> Type pstree in console.

Kermit.

detto · 2006-10-02 20:18:30

Thank you kermit!!
Everything checked. My Daemons set up works

LB06 · 2006-10-02 21:43:33

DAEMONS=(syslog-ng !pcmcia @acpid network @ntpd netfs @crond @lisa !httpd @hal !sshd !mysqld @laptop-mode @gensplash kdm)

This is my array. Btw, nice to see the dbus dep has been included in the hal rc script

detto · 2006-10-02 22:08:54

So is acpid
You don't need to list it there

hehejo_ · 2006-10-03 08:45:54

DAEMONS=(syslog-ng klogd @network portmap @laptop_mode !fam @hal !acpid @cpudyn @uptimed !pcmcia !hotplug)

may someone look on my list? I'm not shure if everything is ok.
It runs well - but it can always be improved.

detto · 2006-10-03 10:53:59

Looks fine to me.
You need portmap? I only need this for fam which you have disabled. Therefore disabling portmap too would make sense
Well, if you need it i would say its good as it is now.

cheers,
detto

hehejo_ · 2006-10-03 12:42:38

Uh, I don't know if I need portmap.
It's in there since first install..

I remove it and look what happens..

Mr.Elendig · 2006-10-03 13:21:08

kdm/kdm shoud be started by inittab instead of rc.conf imo. It's a more elegant and "correct" way.

If you are not mounting any network shares at boot (like remote host etc. and are using dhcpcd then you can save quite a bit of time by doing network in the background.
Just my 2 cents (not aimed at anyone in special)

yankees26 · 2006-10-03 20:55:19

DAEMONS=(syslog-ng !hotplug !pcmcia @network @fam crond)

Aside from the removal of netfs and the addition of fam and of course the added @'s its pretty much default. Its open to critique of course.

Just an esthetical comment. You can remove the:
!hotplug !pcmcia
because these daemons don't exist anymore (they were obsoleted by udev). It will unclutter the DAEMONS lines (intead of having them commented out)..

yankees26 · 2006-10-04 00:19:54

Ah, will do.

T-u-N-i-X · 2006-10-04 01:31:35

DAEMONS=(syslog-ng cpufreqd acpid ifplugd network @named @crond !gpm @sshd !samba hplip cups @alsa portmap @fam dbus hal bluetooth gdm)

What do you guys think ? Is this one ok ?

dolby · 2006-10-04 07:05:29

excuse my ignorance but i see most of u have fam added to the daemons. i have it installed but not added to daemons. is there any reason i should add it too?
just for the record mine is

DAEMONS=(syslog-ng network hal @alsa @netfs @crond)
