since i don't have enough anguish in my life, i thought i might take
today to see if i can migrate from devfs to udev on my 8xx board. at
the moment, with a 2.6.11.7 kernel, i have:
busybox-1.00
networking with the I2C/SPI/SMC1 patch installed
devfs
JFFS2 support in kernel (but no partition definition yet)
before i start reading up on udev, any guidance on whether this will
be straightforward, or will i want to slit my wrists by lunch time?
thanks.

for me, this was quite straightforward on a 405 board. you should
remeber to create two device nodes in your filesystem, though:
crw-rw---- 1 root root 5, 1 2005-04-04 04:03 console
crw-rw-rw- 1 root root 1, 3 2005-02-20 11:39 null
else it won't work...
one thing to note is that udev is quite slow on bootup (at least here).
after init is started some initial device nodes are created, this takes
like 5 to 10 seconds here. i don't know if there is a way to decrease
that time:
Freeing unused kernel memory: 92k init
INIT: version 2.86 booting
Mounting a tmpfs over /dev...done.
Creating initial device nodes...done.
that is a bit annoying... but i didn't put any energy in resolving that
issue yet, so maybe it's easy ;)
hth,
andre
