How much space do I need on "/" for a 7.4 to 8 stable upgrade?

I did a 5.5 -> 8.1 upgrade (no intermediate installs!) on a system with a
256MB root a few years ago and didn't have any problems.  As Adam said, get
rid of any /boot/*/*.symbol files.  With symbols, a kernel directory could
be 50-70 MB, but without, you're looking at only 5-15 MB.  My root is only
90MB used, so there should be quite a bit of space you should be able to
free up still.  Try deleting web browser cache dirs or ccache trees in
~root.

All the files in /rescue is hardlinked to each other, so they only consume
4MB total.
