I think this is fixed already.

What about these names:

Desktop machine (all files in one partition, recommended for new users)
Desktop machine (separate partition for home directories)
Multi-user workstation
Storage server (big /var)

Storage server will be a new recipe, proposed by Margarita Manterola.
It will give probably what you need.

The installer could set this option automatically.

I agree that this mount option is very usefull and making it defaulut
for (all of some of?) the recipes in partman-auto is a good idea.

I think this has happened to other users also but the reason is unknown.
In order to make the situation more clear it will be helpful if you can
post the contents of the directory /var/log of the installer.  In the
installed system you can find it saved in /var/log/debian-installer.

Thanks for you for your suggestions.
