Good pointer, I was missing this bit. Thanks.

In the default configuration the binaries (and I mean all of them!) would
be placed under /usr/lib/oracle, since this is a hardcoded path in all
places.
I will also offer a "WITH_BSDHIER" option which will root the installation
into /usr/local/oracle and just make a symlink under /usr/lib. Should I
rather make this the default ? ;)
There are no libraries (or other binaries for that fact) installed outside
the Oracle hierarchy (this is the general strategy for Oracle RDBMS products
at least). So I guess it very nicely fits into the "enduser" picture you
describe above. I'm just wandering whether a /compat/linux rooted
installation would make sense.
I am still interested to hear opinions from Oracle DBAs/users on this
subject -- would you need this option ?

Thank you for your time.
