It's a technical reason.  We don't install the RPMs in the regular way
(ie. using rpm), but instead we unpack them.  We *used* to install the
RPMs in the regular way into a chroot, but it was a gigantic pain in
the rear the whole time, and we were glad to get away from doing that.

In any case, installing the RPMs like that didn't really solve the
problem, it just added a lot more complication for what is in practice
only a minor issue.

(The way forward in some distant future febootstrap 4 is to install
the RPMs in a virtual machine using kickstart or the equivalent
mechanism on other distros ...)

Try the simpler example from the blog to make sure it's generally
