Probably that you shouldn't have downgraded savecore by updating it
:-).  savecore now uses devname() but devname() is too unreliable to
use for anything except informational output.  There are several
failure modes.  When devname() can't find the device name by looking
up dev.db or using sysctl kern.devname, it invents a name of the above
form.  Apparently, the device name "ad0s1b" is not understood by the
kernel when savecore is run (early in /etc/rc).
