freebsd/usr.sbin/sysinstall/media.c
Rebecca Cran 7ef1629be1 USB probing often takes a long time and finishes finding devices after init 
has started. In the case of sysinstall, this means that it has already built
its list of devices before probing finishes. Add a hint for users who have
booted from a USB stick only to find that sysinstall can't find it.
