Description SpanKY gentoo-dev 2008-01-18 11:51:15 UTC
i dont know what the middle ground is here, but when i set RC_COLDPLUG=no, i fully expect udev to not do a single thing wrt starting services.  i have net.eth0 (which is physically damaged) get coldplugged on me and causes networking problems until i login locally and stop the init.d script.  net.eth6, unlike net.eth0, is added to my default runlevel and has the network settings i actually need.

Comment 1 Matthias Schwarzott gentoo-dev 2008-01-31 13:06:13 UTC
This could be a solution:

In udev-start:

touch /dev/.udev_no_rc_call
... usual udevtrigger ...
udevsettle
rm /dev/.udev_no_rc_call

And in net.sh (that runs the services) do:
if [ -e /dev/.udev_no_rc_call ]; then
  exit 0
fi

Comment 2 Matthias Schwarzott gentoo-dev 2008-01-31 13:16:10 UTC
Second possibility (same effect just using nicer interface):

Inject a variable into the udev-events:
udevadm control --env do_not_run_rc=1
udevtrigger
udevsettle
udevadm control --env do_not_run_rc=

Comment 3 Roy Marples 2008-01-31 23:38:36 UTC
OpenRC now says if rc_coldplug=no, ignore udev coldplug requests. This has a knock on effect of the udev-postmount script not running. I don't know how important that is to udev with regard to this.

This has been implemented in udev-118-r1.
Comment 5 Alexey Shvetsov gentoo-dev 2008-02-01 21:38:29 UTC
Hmm...
I have latest versions of openrc and udev-118-r1
in rc.conf rc_coldplug=yes but no interfaces starts automaticaly at boot

Is this more than slightly related to the content of this bug?
I guess this belongs to bug 208245.
