Ooooh, we can give you gotcha's ... no doubt about that:-):-)

There are a few answers like "Because [RPM|FSSTD|LSB|...] decrees it",
but the basic thought behind all those would be that any "system level
RPM" should put things in predictable places... Usually system level
tools would go into /usr/sbin or /sbin (though the "s" stands for
"statically linked"...not "system tools":-). The tarball put things in
an alternative place, where it is supposed to ... /opt (which stand
for "optional", although many things put there aren't especially
optional:-) is meant for things that aren't part of the distro
packaging scheme, but aren't really locally developed (as you all
know, /usr/local used to be the dumping grounds of such packages).
I'm too rusty a Solaris user to rightly remember, but I think it has a
similar "structure" to things...:)
I'm sure you'll get a few diverging/converging answers to this effect,
but ... that is basically it:).
