In the general case I'd agree with you.  Disk is cheap.  And almost
all system have split / and /usr.

In the small, embedded world, however, reducing the 4.1M and 12M to
600k and 1200k respectively is a huge win.  We at Timing Solutions run
FreeBSD in 16M or 32M or 64M parts where an extra 6M is a huge win.
Especially on the 16M part.  The minimal system that I had went from
14.7M to 7.9M which pushed the 16M part from being useless to being
useful (we have about 6M of binaries and sundries that go onto these
systems).

I also plan on putting together a small 16M X terminal for the iopener
with this if all goes well.
