MOUNT_LFS(8)						    BSD System Manager's Manual 					      MOUNT_LFS(8)

NAME

     mount_lfs -- mount a log-structured file system

SYNOPSIS

     mount_lfs [-bdins] [-N nsegs] [-o options] special node

DESCRIPTION

     The mount_lfs command attaches a log-structured file system special device on to the file system tree at the point node.  Both special and
     node are converted to absolute paths before use.  In addition, the lfs_cleanerd(8) utility is invoked to clean the file system periodically.

     This command is normally executed by mount(8) at boot time.

     The options are as follows:

     -b      Instruct the cleaner to count bytes written, rather than segments read, to determine how many segments to clean at once.

     -d      Run lfs_cleanerd(8) in debug mode.

     -i      Instruct the cleaner to use filesystem idle time as the criterion for aggressive cleaning, instead of system load.

     -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.

     -N nsegs
	     Clean nsegs segments (or bytes' worth of segments if -b is also specified) at a time.

     -n      Don't start lfs_cleanerd(8) on the file system.

     -s      Cause lfs_cleanerd(8) to read data in small chunks when cleaning the file system.

MOUNT_CD9660(8) 					    BSD System Manager's Manual 					   MOUNT_CD9660(8)

NAME

     mount_cd9660 -- mount an ISO-9660 filesystem

SYNOPSIS

     mount_cd9660 [-egjr] [-o options] [-s startsector] special node

DESCRIPTION

     The mount_cd9660 command attaches the ISO-9660 filesystem residing on the device special to the global filesystem namespace at the location
     indicated by node.  This command is normally executed by mount(8) at boot time.

     The options are as follows:

     -e      Enable the use of extended attributes.

     -g      Do not strip version numbers on files.  (By default, if there are files with different version numbers on the disk, only the last one
	     will be listed.)  In either case, files may be opened without explicitly stating a version number.

     -j      Do not use any Joliet extensions included in the filesystem.

     -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.

     -r      Do not use any Rockridge extensions included in the filesystem.

     -s startsector
	     Start the filesystem at startsector.  Normally, if the underlying device is a CD-ROM drive, mount_cd9660 will try to figure out the
	     last track from the CD-ROM containing data, and start the filesystem there.  If the device is not a CD-ROM, or the table of contents
	     cannot be examined, the filesystem will be started at sector 0.  This option can be used to override the behaviour.  Note that
	     startsector is measured in CD-ROM blocks, with 2048 bytes each.

SEE ALSO

     mount(2), unmount(2), fstab(5), mount(8)

BUGS

     POSIX device node mapping is currently not supported.

     Version numbers are not stripped if Rockridge extensions are in use.  In this case, accessing files that don't have Rockridge names without
     version numbers gets the one with the lowest version number and not the one with the highest.

     There is no ECMA support.

HISTORY

     The mount_cd9660 utility first appeared 4.4BSD.
