Ok maybe i shouldn't of installed udev(cant remember why i did)

Installing udev is a good thing IMO. I'm really impressed with it now.

since i installed it on my Debian unstable box ive lost my /dev/cdrom and /dev/dvd links.

These are created for me by udev.rules lines:

BUS="ide", KERNEL="*[!0-9]", PROGRAM="/bin/cdcap 'read DVD' %k", RESULT="1", NAME="%k", SYMLINK="dvd" BUS="ide", KERNEL="*[!0-9]", PROGRAM="/bin/cat /proc/ide/%k/media", RESULT="cdrom", NAME="%k", SYMLINK="cdrom"

where cdcap is a small script:

#!/bin/bash

if [ -z "$2" ] ; then echo "Usage: $0 <capability> <drive>" ; exit 127 ; fi fieldno=$(sed -n -e '/^drive name:/{;s/ */\n/g;p;q;}' /proc/sys/dev/cdrom/info|grep -n "$2"|cut -f1 -d:) if [ -z "$fieldno" ] ; then echo 0 # not a cdrom? else sed -n -e "/$1/{;s/ */ /g;p;q;}" /proc/sys/dev/cdrom/info | cut -f$fieldno fi

Those are tabs in the slashes, in case they don't show up right.

I also don't seem to have any swap space anymore

Check /etc/fstab - if you were using devfs before, it might say /dev/ide/really/long/path/part3 or something that now wants to be /dev/hda3 or similar again. You could even have /dev/swap if you set udev up for that, but I'm not sure there's much point.

Is adding two lines to /etc/udev/links.conf the best way of setting up /dev/cdrom and /dev/dvd device nodes?

That would work if you're using your udev config on only one system. "Best" depends on what your aim is.
