I went to kernel.org/pub/linux/utils/kernel/hotplug and read udev-FAQ  
and udev_vs_devfs both of which mentions how great udev is and how bad  
devfs is. I even read  
http://www.kroah.com/linux/talks/ols_2003_udev_paper/Reprint-Kroah-Hartman-OLS2003.pdf.

Wow. udev seems to be a "musthave". The problem is: none of these  
documents EVER mentions HOW to install and use it !

In kernel.org/pub/linux/utils/kernel/hotplug, I see various files but  
no mention of what they are or how to use them.

Are you developing this software for use only by people with a Ph.D in  
Linux Software Engineering or for everyone ?

I do know my computer's hardware fairly well, but I'm still working on  
understanding Linux's kernel. So even if I installed udev I wouldn't  
know enough about what was happening to be able to at least submit a  
bug report to help you folks develope this software. But Joe Blow in  
Madison,WI might be nearly a Linux expert but you won't get any help  
out of him because he can't install it either.

I don't seem to really have a use for udev at the moment so I'll  
follow: "If it ain't broke, don't fix it". Though I'll need it if devfs  
support is dropped from the kernel.

Time for me to go back to scratching my head about iptables, ISO  
models, FIB,neighbour table, etc, ad nauseum. Ok. The data comes in the  
modem, hits iptables. Does route and arp play a role in this ? When  
does it go to the kernel?.......AHHH! nuts.

Bye.

Did you look in the udev tarball itself?  :)

In there you will see README file with lots of info on how to build and
install udev.  A HOWTO-udev-for-dev file which explains one way to set
up udev to manage your /dev, and a very good HOWTO on building udev
rules in the docs/ directory (along with some other good documentation.)

If that isn't enough, please let us know.

thanks,

greg k-h

No I have not looked in the tarball. There wasn't any indication in the  
udev-FAQ that I should look there for documentation. A README file in  
http://kernel.org/pub/linux/utils/kernel/hotplug/ pointing people to  
those docs would be nice. And/Or make it item #1 in the FAQ. The FAQ  
and README files are the first two files that I look for when I go  
looking for software on a website.

Unless covered by the docs, an explanation of the files in the  
directory should be included in the README file also.

I'll read them also. Thanks.

if you download a tarball full of source where else would you expect 
documentation ?
an included README or INSTALL file is _very_ common in source tarballs

kernel.org is not a "website" per say, but rather a collection of files
on a ftp server that happens to have web access :)

The README within the udev tarball that you didn't read?  :)
Patches gladly accepted.

Anyway, udev doesn't have a "real" website, as you have found out.
Anyone care to make one up and send it to me so I can add it to the
kernel.org site so stuff like this doesn't happen again?

thanks,

greg k-h

Ouch. That burns a bit.

Um, in the tarball itself? In a seperate tarball, only via a website,  
or non-existant, or other. Take your pick.

There are several tarballs in that directory. All of which, to me  
anyway, have to do with udev. What tells me which ones to get? Should I  
get them all because they are there? Not unless I'm told to. Read my  
first message again this time carefully.

My first message to this mailing list was not meant to be a smart-ass,  
ticked-off remark and it wasn't. It was meant to point out to the  
developers that maybe they should "consider" giving somebody an EASILY  
found pointer.

Flame mode off. And I'm gone. Still subscribed though. Further flames  
will be ignored.

I read HOWTO-udev_for_dev. I don't have a program called "chkconfig",  
I'd have to study the scripts to see what they do, and I don't have a  
rc.sysinit file either so since I don't *need* udev now, I'll come back  
later. I'm tackling iptables for a while longer.

I hate it when packages have their 'make install' install scripts in my / 
etc/rc.d directory. They don't work and I have to clean up the  
directory afterwards. CUPS for example.

Thanks for the pointers Greg & Arun.

i abuse DESTDIR for this purpose ...
`make install DESTDIR=$HOME/tmp/`
then i can rip out the files that i'll never use ... pretty sure the udev 
install supports this but dont quote me on it ;)

at any rate, i think we all agree that a nice little website with an 
about/howto {install,use} would be good ... just no one seems to want to 
write said website ...

That file was for intregrating into a old version of Fedora.  I doubt it
still applies to the recent versions as udev is now included in
FC3-test.

Actually all distros now seem to support udev already.  So I recommend
just upgrading to the latest version of your favorite one and using the
verison of udev that's included in it.  

As /dev management is pretty tricky to get just right in the startup
scripts, I'd rely on your distro to get it correct.

And if you're using a distro that doesn't support udev in it's latest
2.6 release, please let me know and I'll go bug them :)

What distro are you using that the included /etc/inid.d/ file doesn't
work properly for?
