Bug 191466 – RC_COLDPLUG=no breaks udev network naming rules

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Marius Mauch (RETIRED) 2007-09-06 06:59:03 UTC]

Not sure if this is an issue in baselayout or udev, or maybe even the network drivers in the kernel:

With RC_COLDPLUG=NO in /etc/conf.d/rc baslayout calls udevtrigger with --attr-match=dev. This causes udev to skip my rules for renaming the network interfaces as their sysfs entries don't have a "dev" attribute:

$ ls -l /sys/class/net/lan0/dev*
lrwxrwxrwx 1 root root 0 Sep  6 08:46 /sys/class/net/lan0/device -> ../../../../../devices/pci0000:00/0000:00:08.0

$ ls -l /sys/devices/pci0000:00/0000:00:08.0/dev*
-r--r--r-- 1 root root 4096 Sep  6 08:46 /sys/devices/pci0000:00/0000:00:08.0/device

This obviously breaks the network init scripts later in the boot process.

baselayout makes no such call - we just start udev.

sure udev-start.sh does the udevtrigger call.
Maybe we need to start up udevtrigger more than once to match all stuff that is not coldplug.
Or redesign coldplug setting for udev completely.

[Comment 3 Matthias Schwarzott 2007-09-11 13:43:47 UTC]

Maybe we can add a call to
udevtrigger --subsystem-match=net
at udev-start.sh

This is implemented in udev-115-r3.

FIXED then.
