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. 4th Berkeley Distribution March 27, 1994 4th Berkeley Distribution

NAME
mount -- mount file systems SYNOPSIS
mount [-adfruvw] [-t ufs | lfs | external_type] mount [-dfruvw] special | node mount [-dfruvw] [-o options] [-t ufs | lfs | external_type] special node DESCRIPTION
The mount command calls the mount(2) system call to prepare and graft a special device or the remote node (rhost:path) on to the file system tree at the point node. If either special or node are not provided, the appropriate information is taken from the fstab(5) file. The system maintains a list of currently mounted file systems. If no arguments are given to mount, this list is printed. The options are as follows: -a All the filesystems described in fstab(5) are mounted. Exceptions are those marked as ``noauto'' or are excluded by the -t flag (see below). -d Causes everything to be done except for the actual system call. This option is useful in conjunction with the -v flag to determine what the mount command is trying to do. -f Forces the revocation of write access when trying to downgrade a filesystem mount status from read-write to read-only. -o Options are specified with a -o flag followed by a comma separated string of options. The following options are available: async All I/O to the file system should be done asynchronously. This can be somewhat dangerous with respect to losing data when faced with system crashes and power outages. This is also the default. It can be avoided with the noasync option. force The same as -f; forces the revocation of write access when trying to downgrade a filesystem mount status from read-write to read-only. noasync This filesystem should not force all I/O to be written asynchronously. noauto This filesystem should be skipped when mount is run with the -a flag. nodev Do not interpret character or block special devices on the file system. This option is useful for a server that has file systems containing special devices for architectures other than its own. noexec Do not allow execution of any binaries on the mounted file system. This option is useful for a server that has file systems containing binaries for architectures other than its own. nosuid Do not allow set-user-identifier or set-group-identifier bits to take effect. rdonly The same as -r; mount the file system read-only (even the super-user may not write it). sync All I/O to the file system should be done synchronously. update The same as -u; indicate that the status of an already mounted file system should be changed. union Causes the namespace at the mount point to appear as the union of the mounted filesystem root and the existing directory. Lookups will be done in the mounted filesystem first. If those operations fail due to a non-existent file the underlying directory is then accessed. All creates are done in the mounted filesystem. Any additional options specific to a filesystem type that is not one of the internally known types (see the -t option) may be passed as a comma separated list; these options are distinguished by a leading ``-'' (dash). Options that take a value are specified using the syntax -option=value. For example, the mount command: mount -t hfs -o nosuid,-w,-m=755 /dev/disk2s9 /tmp causes mount to execute the equivalent of: /sbin/mount_hfs -o nosuid -w -m 755 /dev/disk2s9 /tmp -r The file system is to be mounted read-only. Mount the file system read-only (even the super-user may not write it). The same as the ``rdonly'' argument to the -o option. -t ufs | lfs | external type The argument following the -t is used to indicate the file system type. The type ufs is the default. The -t option can be used to indicate that the actions should only be taken on filesystems of the specified type. More than one type may be specified in a comma separated list. The list of filesystem types can be prefixed with ``no'' to specify the filesystem types for which action should not be taken. For example, the mount command: mount -a -t nonfs,hfs mounts all filesystems except those of type NFS and HFS. If the type is not one of the internally known types, mount will attempt to execute a program in /sbin/mount_XXX where XXX is replaced by the type name. For example, nfs filesystems are mounted by the program /sbin/mount_nfs. -u The -u flag indicates that the status of an already mounted file system should be changed. Any of the options discussed above (the -o option) may be changed; also a file system can be changed from read-only to read-write or vice versa. An attempt to change from read-write to read-only will fail if any files on the filesystem are currently open for writing unless the -f flag is also specified. The set of options is determined by first extracting the options for the file system from the fstab table, then applying any options specified by the -o argument, and finally applying the -r or -w option. -v Verbose mode. -w The file system object is to be read and write. The options specific to NFS filesystems are described in the mount_nfs(8) manual page. FILES
