[Solved]Howto use portage after pkg unpacked in to /var/...

[pingtoo]

Hi,

currently I have usage problem for package (buildah) I like to debug and possible alter its behavior.

I know I can use emerge to unpack the package into /var/tmp/portage/app-containers/buildah, but I don't know how to do compile and install using content in /var/tmp/portage/app-containers/buildah. Can someone give me some instruction on how? much appreciated!

Is ebuild (/usr/bin/ebuild) what you're looking for?
Lets you do the different stages one by one of installing a package.

• ebuild /var/db/repos/gentoo/app-containers/buildah/buildah-1.41.0.ebuild prepare
• Inspect, edit sources, etc.
• ebuild /var/db/repos/gentoo/app-containers/buildah/buildah-1.41.0.ebuild install
• If you can test it from the installation staging area, then test it here. Otherwise, ebuild /var/db/repos/gentoo/app-containers/buildah/buildah-1.41.0.ebuild qmerge to install it to the live filesystem.
• When done, ebuild /var/db/repos/gentoo/app-containers/buildah/buildah-1.41.0.ebuild clean. This wipes out the package's directory under /var/tmp/portage, including any changes you made to the source. Be sure to have a manual copy of any changes you want to keep.

When finished, use diff -u to compare the prepare'd sources to your changes. Save the result in an appropriate file under /etc/portage/patches so that future builds using emerge apply your changes automatically.
