What would make more sense to me for thsi would be a kernel name that was recognised by teh final boot stages as being an exeprimental kernel and moved to the new location only on successful boot.. Once you have successfully booted it, then you delete the kernel[-1] and do the replacement that "make installkernel" now does. > >> Regards >> Steve > > > _______________________________________________ > freebsd-current@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-current > To unsubscribe, send any mail to > "freebsd-current-unsubscribe@freebsd.org" >
