Options are specified with a -o flag followed by a comma separated string of options. See the mount(8) man page for possible options and their meanings.
The mount_std utility examines its zeroth command-line argument (the name by which it was called) to determine the type of file system to be mounted. If it is called by a name which does not end in "_ fsname", mount_std will assume (for compatibility with mount(8)) that the zeroth argument contains only the name of the file system type. The mount_std utility is normally installed with appropriate links to commands for the distributed file systems which can be mounted in this way; for information on the function of each file system, see the manual page for that specific mount_ fsname utility.
Refer to the following manual pages for detailed information on these file system: devfs(5), fdescfs(5), linprocfs(5) and procfs(5).
