FWIW, the upgrade won't proceed until you pick a disk that has something
like a root file system on it. There is a fair chance that you can find
the proper disk by just pressing enter a number of times, unless you
have multiple root filesystems (as I assume could be the case with
diskless setups).
See is_rootdisk() in /usr/src/distrib/miniroot/install.sub:
$ sed '/^is_rootdisk/,/^}$/!d' /usr/src/distrib/miniroot/install.sub
is_rootdisk() {
local _d=$1 _rc=1
(
make_dev $_d
if disklabel $_d | grep -q '^ a: .*4\.2BSD ' &&
mount -t ffs -r /dev/${_d}a /mnt; then
ls -d /mnt/{bin,dev,etc,home,mnt,root,sbin,tmp,usr,var}
_rc=$?
umount -f /mnt
fi
rm -f /dev/{r,}$_d?
return $_rc
) >/dev/null 2>&1
}
