Create a gpkg for gentoo-sources with built objects

[sdauth]

Hello,
Can it be done ? I tried to play with quickpkg but it only includes the source as expected.
Is there any tool I can I can use to create a valid gpkg of current installed kernel including the built objects ? (So when fetching the binpkg on my laptop from this build host, the compiled source is installed using this gpkg and I just have to run make install)
Right now, I just create a tarball of /usr/src/linux on the build host, this tarball is fetched & extracted once gentoo-sources is installed (using a rule in /etc/portage/env) on each laptop, which doubles the install time. So it would be really nice to directly fetch the compiled gentoo-sources instead.

Thanks.

Perhaps you could use emerge(1)'s --binpkgonly / -B option?

I already use binpkgonly, but this fetches the gentoo-sources created by portage on the build host (pure source, not compiled)
What I want is replace this gpkg with a new one with the compiled source, with the same name (ex: gentoo-sources-6.18.32-r2.gpkg.tar) in order to be picked up by the laptop using binpkgonly.

Or if not possible, maybe trick portage on each laptop to make it look like gentoo-sources was installed correctly (skipping the fetch & extraction to /usr/src/linux) although I'm not sure about the metadata part here.
I remember something similar was posted a long time ago but can't find the thread again.

then a post_pkg_postinst rule in /etc/portage/env/sys-kernel/gentoo-sources

Code: Select all

post_pkg_postinst() {
...
}

to trigger the fetch & extraction of the manually created tar.gz (shared through http on lan) of /usr/src/inux with the built objects.
This is what I already use but as I said in my first post, this involves to fetch & install the full (not compiled) gentoo-sources first.
Usually it is not a big deal but with the higher frequency of kernel updates recently, any optimization is welcomed

As a last resort, I could also leave portage out of the equation (remove gentoo-sources from @world on my laptop) and manually fetch & extract the compiled sources tarball from the binhost with a simple script.

As my system was set up long before any of the Gentoo ready-built kernels, as as I build my laptop's kernel on my desktop machine (it would take forever on the laptop), I use scripts. After all, gentoo-sources neither builds nor installs the kernel, that's always been manual make && make modules_install && make install.

I package the kernel for my laptop using the procedure on the wiki page I wrote about building kernels from userspace. (You can replace "kmake" with "make" in the procedure if you don't want the full userspace build stuff.)

[sdauth]

Yes, I'm aware of make dir-pkg (or tarxz-pkg), this indeed allows to fetch the built kernel (vmlinuz & modules) in a convenient small archive but doesn't include the full source with built objects.
The reason I want the source is that sometimes I want to add a module or make a small config change and it allows me to quickly rebuild using the existing built objects. It is very handy with this core2 era laptop because otherwise, it's 1h30 build time with a clean source.
From what I read so far, quickpkg is unable to include the built objects of gentoo-sources.
I admit I have a particular use case so I won't complain too much about it of course Maybe just handle it outside of portage with a simple script is the way.

What you describe is precisely the use case for gentoo-kernel with your own built binpkg from that. The whole point of gentoo-sources is Portage doesn't know anything except the source files.

I interpreter this question as is there a existing tool(s) or know how on how to create gpkg for any package with .ebuild file or not.

As for this specific gentoo-sources case, I wonder if one can use the "ebuild" command to do something.

will "ebuild /path/to/modified-gentoo-source.ebuild qmerge" or "ebuild /path/to/modified-gentoo-source.ebuild postinst" give that opportunity to create the gpkg?

qmerge will create a binpkg from the files in the image directory. quickpkg will take files installed by the ebuild listed in CONTENTS in /var/db/pkg from the live filesystem. Nothing will make it pick up compiled objects in /usr/src/linux.

Really, this is precisely what gentoo-kernel is for. Build it, enable FEATURES=buildpkg or use quickpkg, and deploy it.

sam_,

Thanks for respond. I realize my question is dumb question after some thinking. To create gpkg for anything is to write a .ebuild, that is gentoo way.
