Hi,
I thought this was fixed some time ago... the /etc/init.d/udev
script now checks if files can successfully be created in the tmpfs
/dev dir:

  # using ln to test if /dev works, because touch is in /usr/bin/
  if ln -s test /dev/test-file; then
    rm /dev/test-file
    log_end_msg 0
  else
    log_failure_msg "FATAL: udev requires tmpfs support, not started."
    umount /etc/udev
    umount /dev
    log_end_msg 1
    exit 1
  fi

(This is from udev version 0.060-1ubuntu1, I'm not sure which version
in debian fixed it).
The problem only occurred if someone was using a kernel that they compiled
themselves, since the debian provided kernels had the required support.

So it's fixed for udev, at least. I thought it had been re-assigned to
linux-2.6 because someone thought the bug was for listing tmpfs in
/proc/filesystems when tmpfs wasn't available.
