[gentoo-catalyst] genkernel-next instead of genkernel?

Hello catalysts, I need to build a systemd-based stage4 with a kernel.


I think this means I need to provide a binary kernel package "out of band" as suggested in the catalyst HOWTO, or switch catalyst to use genkernel-next.


I prefer to teach catalyst to use genkernel-next, because it simplifies my build system to have catalyst do everything.  Iit was pretty easy to get this going.  I'm attaching my tiny patches (against the 2.X branch) as a starting place.  These patches switch catalyst entirely away from genkernel and to genkernel-next, which does what I need but is a little heavy handed...


If this looks like a useful approach i'll be happy to try to integrate these changes more cleanly, perhaps by letting the user select (in the catalyst-spec) between genkernel and -next.


Feedback is welcome.

the chances of catalyst switching to genkernel-next is pretty low
to non-existent.  they forked an old version of genkernel and dropped
support for things like cross-compiling.

It's not forced to use genkernel-next to build systems-based stage4.
Actually, I have successfully built gentoo@ppc64le with systemd by
genkernel.

​I was under the impression that gentoo-next was required in order to use
systemd. I thought I was unable to emerge genkernel at all while systemd
was installed. Has that problem been fixed?​
