The “catch” in all of this, however, is that even after all of this there seems to remain things from the ISO burning: just try “mount -t iso9660 /dev/sdb” and it does.

And when trying to just creating a new one here, it pops an error of “mkvfat” or something like that, as in “device busy”. Yast Partitioner sees no partitions at all inside this USB device, yet when plugging the USB file browser notifies a new volume was detected! Showing indeed all ISO’s contents. Added notes on DHCP broadcast packets for FreeBSD.
