Actually,
On most all Unixes (except AIX) /usr/local is the standard for
installed applications. This includes the BSD family of which AIX is a
child.
There was an /opt standard on Solaris for several years primarily
for the reason you cite (export via NFS), but they too have preferred
/usr/local in recent releases. I'm finding also that most if not all
Linuxes are looking to /usr/local as well. This has been specified by the
Linux Standards Base http://www.linuxbase.org consisting of more than 25
industry giants including IBM and Oracle.
The reason I say all that is to say this:
Of the sixteen or so third-party *.tar.gz applications I've
installed recently over 4.3.3 or 5L, they have *ALL* been tarballed as an
install to /usr/local. To put them elsewhere (via --prefix) would be to
install them in other their intended directory.
Being a relative newcomer to the AIX crew (in comparison to some of
you folks here--I've got 7 years AIX), I've tended toward obtaining software
from BULL or UCLA just to keep it in the SMIT *.bff packaging scheme.
However, most any other package I've had to install, I've just let the
package dictate it's location (which most often tends toward /usr/local)
What do some of you vets see as the primary downfall of management of
packages over /usr/local rather than other locations, is this prdominantly
an NFS-shared situation, or speaking in general, and what are your
practices?
Thanks.

Subject: Re: Common shared filesystem
/usr/common or /usr/shared is the standard I've seen.
However, I once worked at one
linguistically-challenged dot-bomb that INSISTED on
/usr/local as a common, NFS-mounted (and read-only!)
repository for its 1200 UNIX machines.
It became an administrative nightmare installing
freeware into /usr/local.
