NAME

mount_ffs, mount_ufs — mount a Berkeley Fast File System

SYNOPSIS

mount_ffs

[-o options] special node

DESCRIPTION

The mount_ffs command attaches the Berkeley Fast File System on the special device on to the file system tree at point node. Both special and node are converted to absolute paths before use.

The mount_ufs form of the command is meant for backward compatibility only. Fast File Systems should no longer be listed as type “ufs” in fstab(5) and instead should be listed as type “ffs”.

This command is normally executed by mount(8) at boot time. The options are as follows:

-o

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.

HISTORY
