I would reserve a tiny bit, just for safety.  (Even if it is only a
couple of blocks.)

As I understand it, the main reason for that safety net was so root
could allocate space no matter what for things like /lost+found.
Also, if you have no free space, the kernel can't do it's
fragmentation-avoiding magic.  On top of all that, I've heard that
ext3 *really* doesn't like it when you totally run out of disk space.

So if you do "tune2fs -r 1024 /dev/whatever", you'll reserve 4MB on
the filesystem.  I hardly think you'd notice 4MB missing.  :-)
