...and a good way for this to happen is by trying to use the 4.2bsd
standalone copy program from the 4.2 distribution cassette.  When our
4.3 package arrived, Berkeley had not enclosed a cassette, presumably
because we were already known to be running 4.2.  I tried using the 4.2
cassette and got the iinit panic.  I grumbled and resorted to manually
bootstrapping the miniroot.  See Appendix B of "Installing &
Operating."  That worked.
