It "works", except when it doesn't. If you can make sure the bundle is
only ever installed in a transaction of it's own, without --root, it'll
probably work just fine. But "rpm from within rpm" does break in some
cases, for example certain chroot install scenarios and more esoteric
cases such as glibc futex implementation changing in the same transaction.
And the breakage will always happen when you least expect it ;)
