+All files are in filesystems, and before you can access any file, its
+filesystem must be mounted. Because of Unix's concept of
+@emph{Everything is a file}, mounting of filesystems is central to doing
+almost anything. This section explains how to find out what filesystems
+are currently mounted and what filesystems are available for mounting,
+and how to change what is mounted.
+
+The classic filesystem is the contents of a disk drive. The concept is
+considerably more abstract, though, and lots of things other than disk
+drives can be mounted.
+
+Some block devices don't correspond to traditional devices like disk
+drives. For example, a loop device is a block device whose driver uses
+a regular file in another filesystem as its medium. So if that regular
+file contains appropriate data for a filesystem, you can by mounting the
+loop device essentially mount a regular file.
+
+Some filesystems aren't based on a device of any kind. The ``proc''
+filesystem, for example, contains files whose data is made up by the
+filesystem driver on the fly whenever you ask for it. And when you
+write to it, the data you write causes changes in the system. No data
+gets stored.

+This section describes the functions for mounting, unmounting, and
+remounting filesystems.
+
+Only the superuser can mount, unmount, or remount a filesystem.
+
+These functions do not access the @file{fstab} and @file{mtab} files. You
+should maintain and use these separately. @xref{Mount Information}.
+
+The symbols in this section are declared in @file{sys/mount.h}.
+
+@comment sys/mount.h
+@deftypefun {int} mount (const char *@var{special_file}, const char *@var{dir}, const char *@var{fstype}, unsigned long int @var{options}, const void *@var{data})
+
+@code{mount} mounts or remounts a filesystem. The two operations are
+quite different and are merged rather unnnaturally into this one function.
+The @code{MS_REMOUNT} option, explained below, determines whether
+@code{mount} mounts or remounts.
+
+For a mount, the filesystem on the block device represented by the
+device special file named @var{special_file} gets mounted over the mount
+point @var{dir}. This means that the directory @var{dir} (along with any
+files in it) is no longer visible; in its place (and still with the name
+@var{dir}) is the root directory of the filesystem on the device.
+
+As an exception, if the filesystem type (see below) is one which is not
+based on a device (e.g. ``proc''), @code{mount} instantiates a
+filesystem and mounts it over @var{dir} and ignores @var{special_file}.
+
+For a remount, @var{dir} specifies the mount point where the filesystem
+to be remounted is (and remains) mounted and @var{special_file} is
+ignored. Remounting a filesystem means changing the options that control
+operations on the filesystem while it is mounted. It does not mean
+unmounting and mounting again.
+
+For a mount, you must identify the type of the filesystem as
+@var{fstype}. This type tells the kernel how to access the filesystem
+and can be thought of as the name of a filesystem driver. The
+acceptable values are system dependent. On a system with a Linux kernel
+and the @code{proc} filesystem, the list of possible values is in the
+file @file{filesystems} in the @code{proc} filesystem (e.g. type
+@kbd{cat /proc/filesystems} to see the list). With a Linux kernel, the
+types of filesystems that @code{mount} can mount, and their type names,
+depends on what filesystem drivers are configured into the kernel or
+loaded as loadable kernel modules. An example of a common value for
+@var{fstype} is @code{ext2}.
+
+For a remount, @code{mount} ignores @var{fstype}.
+
+@c This is traditionally called "rwflag" for historical reasons.
+@c No point in confusing people today, though.
+@var{options} specifies a variety of options that apply until the
+filesystem in unmounted or remounted. The precise meaning of an option
+depends on the filesystem and with some filesystems, an option may have
+no effect at all. Furthermore, for some filesystems, some of these
+options (but never @code{MS_RDONLY}) can be overridden for individual
+file accesses via @code{ioctl}.
+
+@var{options} is a bit string with bit fields defined using the
+following mask and masked value macros:
+
+@table @code
+@item MS_MGC_MASK
+This multibit field contains a magic number. If it does not have the value
+@code{MS_MGC_VAL}, @code{mount} assumes all the following bits are zero and
+the @var{data} argument is a null string, regardless of their actual values.
+
+@item MS_REMOUNT
+This bit on means to remount the filesystem. Off means to mount it.
+@c There is a mask MS_RMT_MASK in mount.h that says only two of the options
+@c can be reset by remount. But the Linux kernel has it's own version of
+@c MS_RMT_MASK that says they all can be reset. As far as I can tell,
+@c libc just passes the arguments straight through to the kernel.
+
+@item MS_RDONLY
+This bit on specifies that no writing to the filesystem shall be allowed
+while it is mounted. This cannot be overridden by @code{ioctl}. This
+option is available on nearly all filesystems.
+
+@item S_IMMUTABLE
+This bit on specifies that no writing to the files in the filesystem
+shall be allowed while it is mounted. This can be overridden for a
+particular file access by a properly privileged call to @code{ioctl}.
+This option is a relatively new invention and is not available on many
+filesystems.
+
+@item S_APPEND
+This bit on specifies that the only file writing that shall be allowed
+while the filesystem is mounted is appending. Some filesystems allow
+this to be overridden for a particular process by a properly privileged
+call to @code{ioctl}. This is a relatively new invention and is not
+available on many filesystems.
+
+@item MS_NOSUID
+This bit on specifies that Setuid and Setgid permissions on files in the
+filesystem shall be ignored while it is mounted.
+
+@item MS_NOEXEC
+This bit on specifies that no files in the filesystem shall be executed
+while the filesystem is mounted.
+
+@item MS_NODEV
+This bit on specifies that no device special files in the filesystem
+shall be accessible while the filesystem is mounted.
+
+@item MS_SYNCHRONOUS
+This bit on specifies that all writes to the filesystem while it is
+mounted shall be synchronous; i.e. data shall be synced before each
+write completes rather than held in the buffer cache.
+
+@item MS_MANDLOCK
+This bit on specifies that mandatory locks on files shall be permitted while
+the filesystem is mounted.
+
+@item MS_NOATIME
+This bit on specifies that access times of files shall not be updated when
+the files are accessed while the filesystem is mounted.
+
+@item MS_NODIRATIME
+This bit on specifies that access times of directories shall not be updated
+when the directories are accessed while the filesystem in mounted.
+
+@c there is also S_QUOTA Linux fs.h (mount.h still uses its former name
+@c S_WRITE), but I can't see what it does. Turns on quotas, I guess.
+
+@end table
+
+Any bits not covered by the above masks should be set off; otherwise,
+results are undefined.
+
+The meaning of @var{data} depends on the filesystem type and is controlled
+entirely by the filesystem driver in the kernel.
+
+Example:
+
+@smallexample
+@group
+#include <sys/mount.h>
+
+mount("/dev/hdb", "/cdrom", MS_MGC_VAL | MS_RDONLY | MS_NOSUID, "");

+@end group
+@end smallexample
+
+Appropriate arguments for @code{mount} are conventionally recorded in
+the @file{fstab} table. @xref{Mount Information}.
+
+The return value is zero if the mount or remount is successful. Otherwise,
+it is @code{-1} and @code{errno} is set appropriately. The values of
+@code{errno} are filesystem dependent, but here is a general list:
+

+@item EPERM
+The process is not superuser.
+@item ENODEV
+The file system type @var{fstype} is not known to the kernel.
+@item ENOTBLK

+@itemize
+

+

+The mount point is busy. (E.g. it is some process' working directory or

+A remount was attempted, but there is no filesystem mounted over the

+
+@item

+
+@end itemize
+
+@item EACCESS
+@itemize
+
+@item
+The filesystem is inherently read-only (possibly due to a switch on the
+device) and the process attempted to mount it read/write (by setting the
+@code{MS_RDONLY} bit off).
+
+@item

+
+@item
+@var{special_file} is not accessible because it is in a filesystem that is

+
+@end itemize
+
+@item EM_FILE

+@code{umount2} unmounts a filesystem.
+
+You can identify the filesystem to unmount either by the device special
+file that contains the filesystem or by the mount point. The effect is
+the same. Specify either as the string @var{file}.
+
+@var{flags} contains the one-bit field identified by the following
+mask macro:
+
+@table @code
+
+@item MNT_FORCE
+This bit on means to force the unmounting even if the filesystem is
+busy, by making it unbusy first. If the bit is off and the filesystem is
+busy, @code{umount2} fails with @code{errno} = @code{EBUSY}. Depending
+on the filesystem, this may override all, some, or no busy conditions.
+
+@end table
+
+All other bits in @var{flags} should be set to zero; otherwise, the result
+is undefined.
+
+Example:
+
+@smallexample
+@group
+#include <sys/mount.h>
+
+umount2("/mnt", MNT_FORCE);
+
+umount2("/dev/hdd1", 0);
+
+@end group
+@end smallexample
+
+After the filesystem is unmounted, the directory that was the mount point
+is visible, as are any files in it.
+
+As part of unmounting, @code{umount2} syncs the filesystem.
+
+If the unmounting is successful, the return value is zero. Otherwise, it
+is @code{-1} and @code{errno} is set accordingly:
+
+@table @code
+@item EPERM
+The process is not superuser.
+@item EBUSY
+The filesystem cannot be unmounted because it is busy. E.g. it contains
+a directory that is some process's working directory or a file that some
+process has open. With some filesystems in some cases, you can avoid
+this failure with the @code{MNT_FORCE} option.
+
+@item EINVAL
+@var{file} validly refers to a file, but that file is neither a mount
+point nor a device special file of a currently mounted filesystem.
