Just make sure you leave room for emergencies.

The directory entries are all the same inode. "du /rescue" will show you
around 5.5 megabytes total.

Um, what else is in your root directory? Do you have all of /usr in
there or something? Even /var isn't likely to take up gigabytes (and if
it is, I'd want it on a separate partition).
For example: on my server, I have:
Filesystem Size Used Avail Capacity Mounted on
/dev/ad6s1a 1.9G 938M 883M 52% /
devfs 1.0K 1.0K 0B 100% /dev
/dev/ad6s1f 291G 133G 134G 50% /home
/dev/ad6s1d 4.8G 1.4G 3.0G 32% /usr
/dev/ad6s1g 147G 16G 119G 12% /usr/scratch
/dev/ad6s1e 4.8G 670M 3.8G 15% /var
/dev/md0 62M 32K 57M 0% /tmp
