udev/hotplug/coldplug in Gentoo

RIV@NVX · Feb 8, 2006, 01:35 PM

Did I get this straight?
1) In Gentoo, hotplug is split into hotplug and coldplug package; colplug searches for hardware, and hotplug loads firmware.
2) Lastest udev has all the functions of hotplug and is supposed to make it obsolete.

I ask because:
1) ipw2200-firmware has dependancy on hotplug
2) In case I remove hotplug/coldplug from boot, udev DOES NOT probe device or load firmware, therefore I see no ipw2200 network device (eth1 in my case) and I need to manually modprobe it.

So:
1) How come I still need hotplug, even I use udev 084?
2) Did I miss something in udev configuration?

In Ubuntu (and other distros), new udev made hotplug obsolete and everything works normally.

The key part you're missing is coldplug.

the "coldplug" package has a coldplug init script which does what you need.

Or you can enable udev coldplugging be editing /lib/rcscripts/addons/udev-start.sh and uncommenting the line regarding coldplug.

I will take a look, thanks for the info. So, if I do that, I can remove both coldplug and hotplug and leave only udev?

In theory yes, but I can tell you that it won't work :P

You need to replicate the coldplug code there in a coldplug init script - I'm trying to get the udev maintainer to do this

It has to happen in an init script otherwise coldplugging of network interfaces (or anything that triggers a script in /etc/init.d) would happen too early and we forceably block this.

I may look into posting such a script if/when I can be bothered to write one as the existing coldplug package works fine for me.
