Wasn't a goal when I wrote the OLPC build system (it was, however, a
goal to create four separate images aka streams (devel/non-devel
msdos-partitioned-ext3-for-usb-sticks/jffs2). I appreciate that goals
change however, I'm not active in the OLPC project anymore.

I was proposing to create an empty dummy RPM package with
Provides: mkinitrd
and also one symlink /sbin/mkinitrd -> /bin/true. If I were to do the
OLPC build system all over again, I'd have one such RPM for dropping
deps that way. Not super nice, but effective.

Historical reasons, don't ask.

Take it easy, it's not like I'm disagreeing with you.

Yes, in 99.999% of all cases (that's five nines for you), it's
absolutely unnecessary to have any static binaries at all in the default
Fedora install. If you had read the archives of fedora-devel-list (which
you Cc'ed yourself) you would have found
- a huge discussion on "static linking considered harmful"; started
by Ulrich Drepper. Some people have even more extreme points of
of view than you. Here's a paper by Ulrich
http://people.redhat.com/drepper/no_static_linking.html
- that early user space in Fedora is increasingly moving to
dynamic linking; that's a good thing; even better if people
remember to kill statically linked binaries :-)
