I don't trust that command. It might edit grub.conf in a way 
that somehow impacts the regular workflow. (Like, overwriting an old 
image, or creating oodles of entries in grub.conf.)
And say I had both lilo and grub installed (on the filesystem), with 
grub in the bootloader; I'd fear that make install might run lilo and 
trash grub in the MBR. No thanks, too much clouds. Also, it can't 
possibly know how to call mkinitrd, because every distro has its own 
stupid required flags (SUSE: requires none and tries to be smart, 
though it will be thankful if you pass it -i and -k, whereas on Fedora 
you need to specify the version, sigh.)
