[rawhide] kernel-install and grubby and ... what's going on?

[Matthew Miller]

It looks like the venerable calls to new-kernel-pkg (from grubby) have been
replaced by kernel-install, which checks if /sbin/new-kernel-pkg exists and
runs that if it does, and otherwise does this stuff
http://www.freedesktop.org/wiki/Specifications/BootLoaderSpec/.

I'm trying to update the cloud kickstart files for F20 (now that F19 is in
the can, right?), and am trying to understand what the plan and migration
path is here. I can't find a feature page for this.

Right now, immediately, the result is no initramfs being created under
appliace-creator. (We're hoping to move _away_ from appliance-creator for
this release, but one step at a time.) I went ahead and added grubby to the
kickstart package manifest, but I'm not sure if that's the right thing.

How is this _supposed_ to be working?

You should probably ask Harald explicitly to be sure, but the current
state of affairs is:

- kernel.spec now requires systemd > <some version that has
kernel-install in it>
- kernel.spec calls kernel-install instead of new-kernel-pkg (which is
provided by grubby)
- kernel-install in Fedora 19 and 20 is patched to call new-kernel-pkg
under the covers for the bootloader config update portions
- kernel-install calls dracut to create the initramfs (I think).
- eventually grub2 will deal with the BootLoaderSpec stuff directly
and kernel-install won't call new-kernel-pkg any longer.

I'm not exactly sure what the timeframe for that last item is, but
it's not in the immediate future.

Which is fine, because it's not like we're gonna support older kernels or
running without systemd.

So until that eventually, it looks like *something* needs to require
new-kernel-pkg so that doesn't get missed. It feels a little odd to put that
requires in the systemd package. Or should we just put the package in it in
@core?
