Steps to reproduce:
only type init 0 or halt, and in remount fs ro init script paniced the kernel

this is the snip of the script:
        MOUNT_FORCE_OPT=
        [ "$(uname -s)" = "GNU/kFreeBSD" ] && MOUNT_FORCE_OPT=-f
        # This:
        #     mount -n -o remount,ro /
        # will act on a bind mount of / if there is one.
        # See #339023 and the comment in checkroot.sh
        mount    $MOUNT_FORCE_OPT -n -o remount,ro -t dummytype dummydev /
2>/dev/null \
        || mount $MOUNT_FORCE_OPT -n -o remount,ro              dummydev /
2>/dev/null \
        || mount $MOUNT_FORCE_OPT -n -o remount,ro                       /
        ES=$?
        [ "$VERBOSE" = no ] || log_action_end_msg $ES
}
