i already went with this approach and it works quite well, my script
is below. it also mounts usbdevfs.
the reason debian uses a script instead of fstab is because 2.0
kernels do not support /dev/pts (and 2.0 kernels are still supported
on potato, they have to be since kernels are not upgraded in a
dist-upgrade) also if for some reason you actually wanted to use devfs
you no longer have /dev/pts. under these conditions mount pukes with
a fstab line, where a shell script can intelligently look at what you
have and do the Right Thing.

yup
here is my `miscfs.sh' script. i linked it to
/etc/rcS.d/S35miscfs.sh, so it runs right after /dev/pts.
#! /bin/sh
set -e
[ "$(uname -s)" = "Linux" ] || exit 0
version="$(uname -r)"
make_devshm()
{
[ -d /dev/shm ] || mkdir --mode=755 /dev/shm
}
mount_devshm_fs()
{
mount -t shm shm /dev/shm
}
mount_devusb_fs()
{
mount -t usbdevfs usbdevfs /proc/bus/usb
}
devshm=$(grep -c '\<shm' /proc/filesystems || true)
devusb=$(grep -c '\<usbdevfs' /proc/filesystems || true)
devshm_mounted=$(mount | grep -c '/dev/shm' || true)
devusb_mounted=$(mount | grep -c '/proc/bus/usb' || true)
if [ $devshm_mounted -lt 1 -a $devshm != 0 ] ; then
make_devshm
mount_devshm_fs
fi
if [ $devusb_mounted -lt 1 -a $devusb != 0 ] ; then
mount_devusb_fs

exit 0
