I would make this

# sed 's/ext2/ext3,ext2/g' <fstab.old >fstab

So that you can still mount the partitions as ext2 if ext3 isn't available
(e.g. using an older kernel or whatever).

Do you really need to reboot? It seems that you could just insmod ext3 and
then `mount -o remount` the relevant partitions.
