The udev guys should hear about hwdetect

I think [edit]tpowa[/edit] ought to send that script to the folks working on udev... Despite not loading modules in parallel, it was faster than uevents, and I think udev could benefit from it.

Then again, I don't really know much about how uevents works, so for all I know this idea might be pretty dumb. lol

Edit: if "No" please explain why. If you feel you need to explain one of the two other poll options, feel free.

Re: The udev guys should hear about hwdetect

hwd deinetely was faster and detected more modules

I didn't mean to imply that you weren't, but I figure you have cooler things to do with your time too. Better to assign a minion. ;-)

Re: The udev guys should hear about hwdetect

The best thing to do here, I suppose, is to incorporate whatever coolness supposedly makes hwdetect better than udev into udev and then submit a patch to the udev devs.

Re: The udev guys should hear about hwdetect

hwdetect was slower than udev. And (despite the parallel module loading), they do the same thing. I am very happy with udev's detection mechanism.

Re: The udev guys should hear about hwdetect

Udev loads ten times less spurious modules on my system - hwdetect should stay dead and buried, bloat that it was.

Re: The udev guys should hear about hwdetect

I don't have any great problems with the latest udev stuff in normal usage. It seems a little slower than the hwd(etect) method(s), but it still within acceptable bounds.

However, I have been playing around with live CDs (larch) and been getting quite ridiculously long uevents times (nearly 2 mins with udev-091-2). A few weeks ago with an older version it was about 30 seconds - which I already found rather long.
Does anyone have any idea what could be causing this? It suggests to me that maybe udev still has a few rough edges.

The main points of functional difference between normal systems and live CDs are: hd vs cd, unionfs, squashfs. But other device/module schemes don't degrade so dramatically under these circumstances.

Maybe someone is aware of another live CD using the latest udev stuff - one which isn't so sluggish?

Always think that been shown another way is a "good thing", as it can sometimes lead you in supprising directions
