That doesn't guarantee the right thing -- it's inverted. It makes it so
that before kernel-devel's %post runs, kernel must be installed. What
Matt needs is a guarantee that kernel-devel is installed (if it will be
installed at all) before kernel's %post runs. Right now the only way to
do that is for kernel to require(post): kernel-devel, which is obviously
not something we want to do.
Actually, I guess that's not the only way -- there is %posttrans . It
has some obvious downsides though, not least of which being if the
transaction fails it'll never get run, it doesn't show up in any
progress information, and AFAIK it's generally just not well tested.
