Enforcing any rigid partitioning scheme is going to cause problems as
it won't (and can't) cover every possible scenario. We've already had a
huge flap about using a RAMdisk for /tmp (and dedicating 50% of your
RAM for it). This has caused MANY utilities to misbehave because they
were using /tmp for temporary files (as they should have) and it would
fill up because it was so damned tiny. Fortunately you can disable this
bit of lunacy and change /tmp back to a disk-based filesystem.

The unification of /usr/[s]bin with the root filesystem is another
biggie that's caused huge amounts of heartburn for admins. There's no
easy way around that one other than having a really big / partition to
hold everything. This one isn't as easy to crack.

Other than that unification thing, all you can do is make
recommendations as to partitioning and layout. Everyone's workload is
likely to be a bit different so "one size doesn't fit all".
