I've done that as part of a restore operation when dropping a tar
backup onto somewhat different hardware (which would seem like a
common enough operation that there would be a nicer approach...). If
you know as much as anaconda does about hardware devices and driver
module names you can build a working initrd manually, but it may be
easier to just install on that or identical hardware and only keep the
/boot contents. And you'll still probably need to know some things
about device naming to fix up fstab and your network configs.
