[gentoo-user] Setting installation directories globally

Hy everybody,

can you please tell me if there is some way to set the install directory
of an ebuild globally without changing the ebuild?
Let me clarify:
I want a few packages to not be merged under / directly but rather to be
located under /something/*.
I understand that the ebuilds contain directives of where to install the
files through src_install(). However I don't believe it would be a good
idea to edit ebuilds manually since it would lead to breakages during
emerge --sync.
So is there some file I can edit to change the install directory for a
certain package?
For example like setting
wireshark /wifi
firefox /stuff
baselayout /
(this is just a rough sketch of what I'm looking for.)

All help would be greatly appreciated!

Many Greetings
Paul

I thought about that too, but wouldn't that more or less create a new
"system". For instance if I emerged a library (say libpcap) with
ROOT="/libs" and then tried to emerge wireshark (which depends on
libpcap) with ROOT="/analysis" I think that wireshark would fail to
start due to "missing" libraries. (Or it would pull in libpcap once more
and merge it into /analysis thus resulting in several installed copies
at once).

Please correct me if I should be mistaken.

Thanks for the help
Paul

To create a very clear directory structure for a small binary Linux
distribution I am planning to build using Gentoo and Portage.

You mean as in compile a bunch of stuff on a Gentoo host, write the 
binaries to say /var/chroot/my-new-distro, chroot into it for testing, 
then write the whole lot to an install media?

Sounds pretty much like how most binary distros are built. In which case
you define ROOT=<whatever> and let rip.

I would create a small -meta ebuild and put it in $PORTDIR/local/. It sets ROOT,
and DEPENDS on everything you want in the binary distro. Then emerge it
