Hi,
when you only need a automatically managed /dev (and not need udev) you
can try the first snapshots of the new 2.6.32 kernel with enabled
devtmpfs. i have tryed this yesterday (linux-2.6.31 +patch
http://www.kernel.org/pub/linux/kernel/v2.6/next/patch-v2.6.31-next-20090925.bz2)
and its works very good for me. you can mount /dev with "mount -t
devtmpfs none /dev" and you have a complete /dev managed by kernel (when
you need udev and it works, udev is very fast with this).

Hi,
I'm trying to migrate an armeb embedded Linux build from a static /dev
to udev. I now have the system coming up with udev enabled, but the
first thing that udev does is disable my console connection. Before
the console starts endlessly spewing "file not found" messages, udev
prints a line like this
tty ttyAMA0: uevent: unsupported action-string; this will be ignored
in a futur
for nearly every device that was in the previous static /dev.
I understand that I can add static rules to udev to fix this, but I
also want to migrate naming conventions to standard names--ttyAMA0
should be ttyS0, etc. I can keep legacy names around with symlinks if
necessary.
So I'm not quite sure how to get started. I have disabled udev's
startup for the moment, so I can get into /sys. Is there a guide
somewhere on how to migrate from a static /dev to udev?
Thanks,
Brendan
