Maybe you could explain why it makes sense to someone whose eyes are too
blind with fury to see it.

Isn't that /bin vs /usr/bin (and /sbin vs /usr/sbin) ?
OS X, curse it, does not staticly compile their /bin executables.
$ otool -L /bin/ls
/bin/ls:
/usr/lib/libncurses.5.dylib (compatibility version 5.0.0, current version 5.0.0)
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 71.0.0)
Debian does an ok job in at least everything is linked against /lib
instead of /usr/lib so you can get somewhere if /usr craps out. This is
at least on par with the FHS.
schwern@mungus:~$ ldd /bin/ls
librt.so.1 => /lib/librt.so.1 (0x40021000)
libacl.so.1 => /lib/libacl.so.1 (0x40033000)
libc.so.6 => /lib/libc.so.6 (0x4003a000)
libpthread.so.0 => /lib/libpthread.so.0 (0x4016d000)
/lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)

Set the way back machine to circa 1998. Linux/PowerPC is just getting off
the ground. I'm sick of running MacOS 9 on my Wallstreet Powerbook so I
install Debian/PowerPC in its early days. One of the more fun things about it
was libc would be broken about one in every three updates which in turn
broke... well everything including the ability to put in a new libc.
As a fledging unix admin I rapidly learned how staticly compile all my
basic utilities. fileutils, textutils, bash, etc... and set root to use
sash (Stand Alone SHell). I learned ALOT from those days.
There's stuff above here
