You can add this in to the spec file that the make command generates.
From my experience in dealing with the spec files from Redhat and SuSE
my advice is, again, don't waste your time.
mkinitrd is done in a post section of the kernel install. Here is what
I used for the 22.214.171.124 kernel:
mkinitrd -v --with=sd_mod --with=libata --with=ata_generic \
--with=ata_piix --with=pata_acpi \
Then the grub manipulation is done with grubby
grubby --add-kernel=/vmlinuz-126.96.36.199 \
So, add these two in to the spec file, and
rpmbuild -bb kernel.spec
rpmbuild -bs kernel.spec
Again, none of this is hard, and you can add it in to the %post section
by hand. The generated spec file is a good working spec file and will
work on RHEL and variants, SuSE and variants, as well as others. But
grubby is specific to RHEL variants last I checked. This is why they
don't generate a %post for you which does all this for you. Similar
with mkinitrd. You can add it in and go from there.
