[gentoo-dev] about modifying an ebuild in local overlay and $FILESDIR

[Christian Bricart]

Hi all,

from time to time, I need to make (and maintain) modifications to an
ebuild from the main tree in my local overlay.
So basically, I create the directory structure from
/usr/portage/<category>/<package>/ under
/usr/local/portage/<category>/<package>/, copy over the ebuild and do my
modifications in the ebuild.
So far how an overlay works ;-)

But if there are references to patches, init-scripts, conf-files, etc
from $FILESDIR w/i the original ebuild, one also needs to copy those
into /usr/local/portage/../../files/ ..

Is it possible to "overlay" such files used in epatch(), newins(),
newconfd(), newinitd(), etc too..?

so i.e:
FILESDIR = "${repository_location}/${CATEGORY}/${PN}/files"
should support a fallback to:
FILESDIR = "${PORTDIR}/${CATEGORY}/${PN}/files"
if not found...
(or actually to the defined $master from the repo used)

Christian

No, this is not possible. It might be possible to implement in
portage, but I don't think it's a very good/workable idea.

As a workaround, you could symlink individual files, or even the
entire files directory.
