And a real time saver, too! Every other boot one of my
partitions is fsck'ed for having been mounted 20+ times.
But if the whole thing was fsck'ed at once, I might be
fck'ed (if I was in a big hurry, for example)

That looks better. Probably a bit rich for /var.
I'd also do 3-4 swap partitions, each 1-2 x the size of your current memory
allocation. Here's why:
- You want your swap roughly paired with your memory allocation.
Swap = 1x or 2x memory is the standard guideline. Usually a new
system has only a fraction of the total possible system memory.
Count on maxing your RAM as the system grows, so you're going to
want an allocation (available swap partitions) of ~2x your maximum
possible RAM. Since having _too_ much swap can result in sluggish
performance (your system swaps and lags while doing it), you'll
want to cut this allocation up into reasonable chunks.
- IMO 1GB is sufficient for /var on a baseline Debian system, where
the primarly use is storing package archives. If you're running
special-purpose servers (particularly logging, usenet, mail,
database, or very large website), you may want to add to your /var
allocation, though creating dedicated partitions may also be
useful. Advantages of partitioning: management of space, ability
to specify performance or security related options (nodev, nosuid,
blocksize, async mounts, etc.). Disadvantages: more things to

You don't *need* any partitions other than /. Creating separate partitions
for /, /usr, /home, /tmp, /var, /usr/local, /boot, /var/spool, /var/www,
etc., is a _convenience_ for better managing your system.
If you don't mount an additional filesystem at a particular point, then that
directory tree simply resides on the parent filesystem. In your case,
/usr/local will be on the /usr filesystem.

If you have more than four partitions, you partition anywhere from 0-3 as
primary partitions, have at least one extended partition, and the remainder
are logical partitions within the extended partition(s).
In practice, I generally use 3 primary, one extended, and the remainder

No, see above. Though it's generally useful practice.
