I am now trying to migrate to udev (I had only filled /dev/ with a
hand-full of mknods in the past), but all the HOWTOs I find are very
distro-specific, while I am working with a home-cooked embedded system,
so I am having trouble with doing this.
I crosscompiled and installed udev with little trouble (it does not
seem to install udevstart for some reason, but I just copied it across)
and moved the contents of /dev/ to /lib/udev/devices/, but left copies
of console and null in /dev/: this much was straight-forward enough.
All the documentation I have seen now either skips forward to
customising rules, or tells you do perform some distro-specific
operation to complete this stage: I am completely lost at what to do
next!
I seem to need to mount a tmpfs on /dev/, then somehow have udev copy
the contents of /lib/udev/devices/ to /dev/, but have no idea how I am
supposed to do this. I have tried explicitly mounting /dev/, launching
udevd and running udevstart, but the moment I mount /dev/ I lose console
and null, so do not get any further. If I run udevstart without mounting
the tmpfs, it just creates an almighty number of useless files in on the
disk (in /dev/) --- I assume the number of files was simply because I
have not yet properly configured the rules.
How do I get udev started properly on an embedded system? I do not
need to worry about lilo/grub, and I do not use an initrd; I assume I
just need to add a few lines to my rcS file, but cannot work out what.
