dirty udev howto

[nestu]

Hello everyone,
I'm going to explain a dirty way on how to get udev running, 
step by step:

* Kernel conf : I recommend taking out devfs. You can keep 
it if you like, but you must not have automatically mount at 
boot ( see Filesystems -> pseudo filesystems ), and you must 
add append="devfs=nomount" to lilo.conf ( no idea for grub 
users yet ). [ ¿Any gub and udev user that is willing to 
feed me back on how to do it? ]

* There are still a couple of problems with boot. A typical 
problem is "WARNING: Unable to open an initial console". To 
solve this, we need to use temporally (untill this issue is 
fixed) a couple of static entries :
	- cd /dev
	- mknod -m 660 console c 5 1
	- mknod -m 660 null c 1 3
will created 2 static entries under /dev. It also seems that 
/dev/pts/ and /dev/shm have to be created, so mkdir 
/dev/{pts,shm} will do the trick.

* Last of all, and depending on our install, we have to add 
the udevstart binary to our boot. udevstart will create some 
entries under /dev.

	- If you don't have initscripts module installed, you'll 
have to edit /etc/init.d/mount and add
	as last line of the start() function (just under the rm -f 
/fastboot /forcefsck line ), like this:
	
	rm -f /fastboot /forcefsck

	/sbin/udevstart

	- If you do have the initscripts module installed, you can 
add this line to /etc/rc.sysinit, nearly 		at the top, just 
after the ". /etc/init.d/functions" line, like this:

	. /etc/init.d/functions

	# populate /dev
	/sbin/udevstart
	
I'm not sure, but sysfsutils seems to be another udev 
dependency. If this works for you with and without 
sysfsutils installed please reach back and tell me, so I can 
add if necessary sysfsutils to udev's DEPENDS. BTW, if you 
also notice that an entry should be created, but it isn't 
(this is the case of /dev/nvidia* AFAIK, for example) please 
tell me aswell; it could be interesting to keep track of 
these type of problems.

HTH,
nestu.
