Filesystem 1K-blocks Used Avail Capacity Mounted on /dev/ad0s1a 1012974 36926 895012 4% / devfs 1 1 0 100% /dev /dev/ad2s1d 5616214 716542 4450376 14% /home /dev/ad0s1e 1012974 22352 909586 2% /tmp . . . Mount points are merely directories where devices are mounted as part of the filesystem. These can be automatically mounted by a listing in /etc/fstab or manually mounted using /sbin/mount. That they show up in df's listing means that something is in fact mounted on it. Typing "mount" at a command prompt will give you a listing of mounted devices like so: /dev/ad0s1a on / (ufs, local) devfs on /dev (devfs, local) /dev/ad2s1d on /home (ufs, NFS exported, local, nosuid, soft-updates) /dev/ad0s1e on /tmp (ufs, local, soft-updates) . . . As none of those above (/proc /net /host) are part of the standard layout (Well, /proc was on 4.x and earlier) some- one at some time has added them. -- --
