	I got very similar results with 15GB, from:
Debian GNU/Linux 5.0r0+edu0~a0 _Lenny_ - Unofficial i386 CD700 Binary-1 20090316-20:49
When using auto-partitioning.

here side by side with their limits definitions:

	/usr <limits> is now 5632 6000 6000
I gather /var has different requirements installing from DVD, yet maybe its minimal size should be set aprox. 2200.

In general these results look reasonable.
The problems I had where on another box, the one with 13GB drive and 512MB RAM.
On top of that I was using guided-partitioning to avoid trashing the other drive.
I realize two reasons for the problem namely debianedufreespace (700+ MB) and swap_1 (1.3GB).
On subsequent installs I lvremoved both from another VT.
The problem is one can't remove or adjust them from within the installer.

To deal with debianedufreespace we'd may modify fsautoresize to check for its existence, verify it's empty and remove it.

For swap_1, I think we should change the limits. On my system it occupied >10% disk-space and brought down the installer, but I read here of working servers with 8GB RAM that would have 24GB swap???
No problem to install but may get >10% disk-space again.
I'd say lower priority and tighter limits: 256 2000 2048, or so?
I'd probably prefer another swap over larger swap.

Odd.
