[gentoo-user] udev and init.d. Should it be running now?

[Dale]

Hi folks,

I was browsing around and noticed that I now have a udev in
/etc/init.d/.  I checked, it is not running but udevd is not running
either.  See below:

> root@smoker / # /etc/init.d/udev status
>  * status:  stopped
> root@smoker / #
> root@smoker / # ps aux | grep udev
> root     30451  0.0  0.0   1888   504 pts/0    R+   16:04   0:00 grep
> --colour=auto udev
> root@smoker / #

This is the baselayout that is installed:

> [I--] [  ] sys-apps/baselayout-1.12.11.1

I seem to recall that baselayout 2 is going to be a service thing but
since I am on baselayout 1, should this be running?  It seems to belong
to the udev package tho according to this:

> root@smoker / # equery belongs /etc/init.d/udev
> [ Searching for file(s) /etc/init.d/udev in *... ]
> sys-fs/udev-141 (/etc/init.d/udev)
> root@smoker / #

You can see from that what udev version is installed too.  I also
checked the elogs and I see no mention of it being changed to a service
or that it needs to be added to a runlevel. 

Also, keep in mind, everything works fine.  I just don't want to add it
to boot or default runlevels and then break something.

Thanks for any advice.  I searched the forums and udev on g.o but didn't
see anything relevant.

In baselayout-1, udev is started directly by baselayout itself, outside
of any init scripts.  In baselayout-2/openrc, an initscript is needed to
start udev.  If you actually read the script, you may notice that the
script will immediately fail if you attempt to run it on a baselayout-1
system, as it isn't needed.  If/when you upgrade to baselayout-2/openrc,
it will automatically be added to the boot runlevel, but only if
baselayout-1 had been previously installed.

In short, don't worry about it. :)

What you say makes sense but why is udev not running on my system
anymore?  I noticed this mostly because I went to single user, KDE
seemed to have a few processes that didn't want to die when I logged
out.  Anyway, I used ps and less to list those processes and noticed
that udev was not running.  It used to be running in the past. 

That got me to looking and that is when I found the init script.  Even
after logging back into KDE, udev was still not running.  I'm sort of
concerned that something is not quite right.  I haven't rebooted in a
week or two either.

Ideas?  Thoughts?

I was surprised to read Jonathan's post, but I see he's right.  On my
x86 machine the status of udev is "stopped" and on ~amd64 it's "started".

But both machines show that /sbin/udevd is indeed running, so I can see
why you are uneasy about your status quo.

Have you tried running /sbin/udevd --daemon from a command prompt? When
I try it I get a message that udevd is already running.

OK.  Now I feel better.  I used your command and now it is running.  I
hope it will run when I reboot.  o_O

root@smoker / # /sbin/udevd --daemon
root@smoker / # ps aux | grep udev
root      2595  0.0  0.0   2204   780 ?        S<s  20:23   0:00
/sbin/udevd --daemon
root      2599  0.0  0.0   1888   512 pts/0    S+   20:23   0:00 grep
--colour=auto udev
root@smoker / #

At least I know udev works now.  I was hoping that something hadn't been
broken and I just didn't notice it. 

Thanks much for the info.  I know how to start it if it is not running
at least.

Using Baselayout 1.12.11.1 & Udev 141 , I get : 

  root:508 default> ps aux | grep udev
    root 659 0.0 0.0 12524 936 ? S<s Sep10 0:00 /sbin/udevd --daemon

So it should be running all the time then but for some reason it wasn't
on mine.  Hmmm.  I'm going to reboot sometime soon and I'll check to see
if it is running then.  I hope this was just a fluke of some kind.

Thanks for all the help.  I'll report back if it doesn't start as it should.

I rebooted, into a new kernel I made a few days ago, and udev is running
without me having to start it or anything.  I dunno what the heck
happened. 
It is running now so I guess it was a fluke of some kind.

Thanks for the help.  I'm off to research building a Phenom II x4
puter.  o_O
