udev init (cont)

[Peter Christy <christy@attglobal.net>]

Firstly, thanks for all the hints & tips guys. I'm starting to get somewhere, 
but need some more information.......

I've compiled udev-012, and after running make install, I've moved the start 
script and renamed it to /etc/rc.d/rc.udev - the correct place for a 
Slackware init script.

I've commented out the line which refers to the functions script (which Slak 
doesn't use) and following Takis hints, replaced <action "string" /bin/true> 
with <echo "string">

I can now start udev manually, and I can see device nodes appear in /udev. 
Further, I can see them appear "automagically" when I plug in usb memory 
sticks! So far, so good......

Now the question remains as to where I should put the command to run udev at 
startup. Slackware has a command right at the top of rc.S (single user init) 
to mount devfs, if it exists. I tried putting something similar in for udev, 
but it stopped the machine recognising pcmcia, and hung shortly thereafter. 
This implies that udev has to be run pretty late in the boot procedure. But 
where? At the end of single user init? In multi-user init (rc.M)? In rc.local 
(right at the end of init)? What criteria have to be met before I can run 
udev?

I assume it has to run fairly early to pick up things like soundcards. At 
present, my /udev only seems to have a very limited number of devices 
present, and doesn't include some things I would expect to see in there, like 
sound or agp. Which brings me to.....:

Although I can see nodes appearing in udev, is there anything I have to do to 
make sure the system is actually using them? For all I know (and I haven't 
got this deep yet) the system could be completely ignoring /udev, and just 
running with the existing /dev! How do I check? Is there anything else I have 
to do?

TIA,
