Maybe he means "put" the usual "contents" of /var (cache, spool, log..) in a given partition? Hence, his question re: more than one /var. If that is what he wants (needs?), there's nothing preventing him from defining separate mount points and partitions for each sub-directory of /var at install time, I would imagine? Although it would make more sense doing so with /home for instance - possibly on large multiuser system, e.g.

You are still talking backwards

You put the partition (/dev/sdXY) on /var not the other way round. You
DON'T put /var on /dev/sdXY

If you imagine there is a conceptual drawing of the tree starting at /
and including all the major mount points - with the non standard mount
points being creatable manually, and somewhere below a list of
unallocated partitions.

Then you could drag any partition (from the unallocated list or from
another mount point) and drop it on mount point you wanted. If that
mount point already had a partition at that point it would warn you, and
if you said continue would move the old partition back into the
unallocated list. If you said don't continue it would leave the old one
where it was and the new one would return from whence it came.

Seems like a good reason to file a bug report, if you ask me. Before
doing so, you might want to actually try an installation like that. Who
knows, maybe the installer will throw an error on the next screen.

Maybe (for the possibly thrown error). I don't know, and I can't test
nowadays because I simply don't have another PC which could receive a
new Debian install. But if somebody can test, I would appreciate
receiving the results.

If I have time, I'll try - once I am clear what it is that you want. I'm
afraid that at the moment I haven't succeeded in understanding what it is
that you want.

In your explanation, try to keep things the right way round: mount partitions
on mount points, not mount points on partitions. At the moment I am very
muddled about what you are trying to do.

P.S. Sorry, Luca. I have only just got round to investigating why my emails
go to you and not the list. It is a problem that I don't usually have, and I
forgot just now. Normally I just click "reply" and it goes to the list. I
usually have to click on "reply special" to reply to the author.

I tried it. It took about 5 minutes in virtualbox-ose.

The installer lets me assign 2 partitions with the same mount point, but
when I hit "Finish partitioning and write changes to disk", I get a red
screen with an error "Two file systems are assigned the same mount point
(/stuff)"..."Please correct this by changing mount points".

At that point I can hit either "continue" or "go back". Both choices
bring me back to the "Partition disks" screen. So it seems it is
impossible to proceed with two partitions sharing the same mount point
-- as it should be.
