[gentoo-user] offline runlevel

[gentoo-user] offline runlevel

[Roger Mason]

Hello,

I am following the runlevel guide
http://www.gentoo.org/doc/en/handbook/handbook-x86.xml?part=2&chap=4 
to set up an offline runlevel for my laptop.  I have in
/etc/runlevels/offline:

rmason # rc-update show offline
               acpid | offline 
            cpufreqd | offline 
                 gpm | offline 
               ivman | offline 
               local | offline 
              pcmcia | offline 
           syslog-ng | offline 
          vixie-cron | offline

Based on the ouput of <scriptname> ineed, nothing there needs
net.eth0.

When I boot into the kernel with this entry in grub.conf:

# For booting GNU/Linux
title  Gentoo Linux 2.6.17-gentoo-r8 (offline)
root (hd0,0)
kernel /boot/kernel-2.6.17-gentoo-r8 root=/dev/sda3 softlevel=offline

the system still tries to start eth0 and then wastes time while dhcpd
times out.

I am not sure what what I have done wrong.  Can anyone help?

Thanks,
Roger Mason

Is it possible that there are still some services set to start in the
"boot" runlevel that would be more appropriate in the "default" or
"offline" runlevel?

Well, the only script in boot that looks promising is net.lo: I had
considered removing it from boot but decided to ask before (possibly) making a
big problem from a small one.

Thanks,

try grepping for need in /etc/runlevels/boot/* and /etc/runlevels/offline/*
to see if any of your boot or offline services has a dependency on
networking..

If there is something that requires net, see if setting
RC_NET_STRICT_CHECKING="lo" in /etc/conf.d/rc will do the trick. If that
doesn;t work, then you may need to remove the service from that softlevel.

Also check for PROGRAM keys in your /etc/udev/rules.d/* to make sure it's
not udev trying to start the device. However, I don't believe there's
anything like that in the default rule sets.

And, I'll second Richard, "emerge ifplugd"

Thanks Richard Joe & Devon, ifplugd is working perfectly for me.

Probably you need one or both of the following in /etc/conf.d/rc:

RC_PLUG_SERVICES="!net.eth0"
RC_NET_STRICT_CHECKING="lo"

BUT, what you probably really want is to emerge ifplugd.  With this
installed, gentoo will detect when there is a cable connected and
startup networking automagically when a cable is inserted.  It should
also avoid timing out on dhcp requests when no link is detected.
