"zipl" as far as I can tell, does not write out the boot sector on the DASD the
same way, or at least it does not appear to. Running zipl on a freshly copied
volume here will not result in a DASD unit that will IPL. "dd" will.
As to traditional - well - dd pretty well predates zipl and chgroot; we were
doing it in the late 1970's. ;)

A chroot and running zipl is more traditional.
