[gentoo-user] emerge --buildpkg --unmerge

["Fatih Tümen" <fthtmn+gentoo@gmail.com>]

Hi,

Is there a way tell portage to build binary package before removing it
from the system?

man emerge says:
--buildpkg (-b)
              Tells  emerge  to  build binary packages for all ebuilds
processed in addition to actually **merging** the packages.
              [...]
              An alternative for already-merged packages is to use
quickpkg(1) which creates a tbz2 from the live filesystem.

I have about 20 packages to unmerge or remerge with new use flags. But
I want to keep binary copies (with old use settings) before unmerging
them. Unfortunately I did not have buildpkg in FEATURES at the time of
emerging them. Doing this now by hand sounds kinda fatigue unless...
the output of --pretend was parsable so I do what I want by..

for pkg in ${PKGS}; do quickpkg --include-config\=y $pkg; done

or by something better?

Thanks for ideas in advance.
