Uh... the last time I built apache from source, it stuck everything
under /usr/local/apache. It uses a conf directory for the config files,
and htdocs for the "data" files...  That is it's default configuration.

You know, this is why I actually suggested looking closer at apache. By
default, everything is crammed in one directory, but if you want to, you
can configure it "six different ways to sunday". That seems to be a big
plus IMO

Is anyone arguing against this? I'm certainly not. But maybe my needs
are more varied than yours. On my local development box, I run multiple
versions of apache, compiled with different versions of php. It really
helps to keep all of apache's stuff centralized, and using things like
rpms actually overly complicates this. Now sure, that's a development
machine, but on the phppgadmin demo server, which is essentially a
production system, I run three different versions of postgresql. In
fact, I need to upgrade two of those (to 7.2.4 and 7.3.2), I shudder to
think about doing that if postgresql forced me to use the /etc/
directory for all of my config files. Now sure, this probably isn't
typical use, but I would say that when it comes time to upgrade major
versions, unless you running an operation where you can have large
amounts of downtime, postgresql needs to have the ability to have
multiple versions install that don't conflict with each other, and it
needs to do this easily. The upgrade process is hard enough already.

Have I wronged you in some former life? I've very little concern for
where you put your data files, and have no idea why you'd think I'd
criticize your setup.
