[gentoo-portage-dev] Proposal of "uncooperative-root" in SUPPORTED_FEATURES

[X dej]

Hello to all,

Summary: I have made many mods to sys-app/portage (2013 version). The result is
a proposal of patch for latest sys-app/portage, see below.

Main result of my mods to gentoo prefix:

  FEATURES=uncooperative-root emerge -bv =firefox-17

now works on EPREFIX on Android-4.1 ARM. I use neither fakeroot nor GNURoot.
root access never required. Distributed as a .tbz2 and a .ebuild by
gentooandroid.sf.net, along with the necessary stage3.

@dol-sen advised me one week ago on #gentoo-portage to post a rebased patch for
HEAD of git.overlays.gentoo.org/proj/portage.git : I just hosted this patch on
sf.net/projects/gentooandroid/files/sys-app_portage-current-HEAD_patch/download
and it is also attached to this post, and to previous post on gentoo-dev
mailing list; Joshua Kinard from there just advised me to post this patch at
gentoo-portage-dev (here).

I request comments and discussions about this patch. Summary:

pym/portage/const.py     + (this is SUPPORTED_FEATURES+=uncooperative-root)
cnf/make.conf.example    ++++++++++++++++++++++++++
bin/ebuild-helpers/emake ++++++++
bin/ebuild.sh            --+++++++
bin/misc-functions.sh    -+++++
bin/phase-helpers.sh     +++++

My aim is to take your remarks into account, then to build an overlay (will be
hosted at endrood.sf.net) with up-to-date versions of all my mods. The final
result will be a tested version of above patch, together with lastest builds
for firefox, squeak, scala, gnucash, ...

Thanks for you attention.
