Is the Debian build process good enough to allow changing the prefix of
where things are installed (including documentation)?
Not all software understands the ./configure --prefix, so sometimes
patches are needed to make sure hard-coded paths are fixed.

Also, what about configuration directories?
Can you have seperate /etc, /usr/pkg/etc, /usr/local/etc (however they are
named) configuration directories and choose to consolidate if needed?
With pkgsrc, configurations files are defined. By default they install to
an examples directory and if don't exist are copied to the real
configuration directory. (Copying into place can be turned off too.) If it
is not copied into place, because a file already exists, then it will tell
you. Also, on deinstall the two files are compared and if different then
the real (or edited) config file is not removed. The final location for
configurations can be defined pkgsrc-wide -- like you can choose to have
all configurations installed to /home/joe/etc. The important key is that
all the software that is built is trained to know that /home/joe/etc/.
Some admins run pkgsrc on FreeBSD boxes and so they do have three complete
software environments (The core FreeBSD, /usr/local for ports, and
/usr/pkg for pkgsrc installations).
Also, I use pkgsrc on some machines as a regular (non-root) user. So I can
have a fourth location for software installations (like /home/reed/pkg/).

Is there a distro called "Actual Linux". I searched. I did find an old
"Linux Actual".
I don't think Gentoo allows it to be installed in multiple places (with
clearly separate config files), such as for different users. Does anyone
know?
