|
|
.Nd mount a Berkeley Fast File System
|
|
.Sh SYNOPSIS
|
|
.Nm mount_ffs
|
|
.Op Fl o Ar options
|
|
.Ar special node
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
command attaches the Berkeley Fast File System on the
|
|
.Ar special
|
|
device on to the file system tree at point
|
|
.Ar node .
|
|
.Pp
|
|
This command is invoked by
|
|
.Xr mount 8
|
|
when using any of the following syntax:
|
|
.Bd -ragged -offset 4n
|
|
.Nm mount Op options
|
|
.Ar special node
|
|
.br
|
|
.Nm mount Op options
|
|
-t ffs
|
|
.Ar special node
|
|
.br
|
|
.Ed
|
|
.Pp
|
|
The
|
|
.Ar special
|
|
device is either a
|
|
.Xr disklabel 8
|
|
UID (DUID) or an entry in
|
|
.Pa /dev .
|
|
If it is a DUID,
|
|
it will be automatically mapped to the appropriate entry in
|
|
.Pa /dev .
|
|
In either case the partition must be present
|
|
in the disklabel loaded from the device.
|
|
The partition name is the last letter in the entry name.
|
|
For example, /dev/sd0a and 3eb7f9da875cb9ee.a both refer to the
|
|
.Sq a
|
|
partition.
|
|
.Pp
|
|
This command is normally executed per file system by
|
|
.Xr rc 8
|
|
at boot time using the
|
|
.Xr mount 8
|
|
command.
|
|
The options are as follows:
|
|
.Bl -tag -width Ds
|
|
.It Fl o Ar options
|
|
Options are specified with a
|
|
.Fl o
|
|
flag followed by a comma separated string of options.
|
|
See the
|
|
.Xr mount 8
|
|
man page for possible options and their meanings.
