The naming convention looks more like Mac OS, though the major device number doesn't match. FreeBSD has been through a number of disk naming conventions, but I'm pretty sure that we never had anything as straightforward as 'disk'. > what was there earlier in FreeBSD before 'block device support' was > dropped? Apart from the name, things used to look similar. Here a quote from "The Complete FreeBSD", written some time at the end of the last century: crw-r----- 1 root operator 3, 131072 Oct 31 19:59 /dev/rwd0s1a brw-r----- 1 root operator 0, 131072 Oct 31 19:59 /dev/wd0s1a The minor number included partition encoding, thus the large number.
