Case-sensitivity is a property of the filesystem. OS X supports several options there,
including standard Unix UFS, MS-DOS, and several flavors of the Mac "native" filesystem,
HFS.

When you initialize/partition a disk with HFS you can choose journaled/non-journaled
and case-sensitive/non-case-sensitive. Unfortunately, in 10.4 you cannot use a case-
sensitive volume as a boot volume. I expect that will change in 10.5 (next spring),
along with full 64-bitness. I currently create my external volumes as case-sensitive.

By the way, HFS is case-preserving, but not case-sensitive, so you can end up with
confusion when you have file names that differ only in case.

This is a hassle, but Apple has been moving to change their legacy non-case-sensitive
filesystem to fully case-sensitive. (In my experience newbies are often quite confused
by case-sensitive systems, so there are some arguments for that approach.)

There are faint rumors that Apple might provide a "modern" filesystem such as ZFS
as an option, but no firm info.
