The automounter is a tool to automatically mount remote file systems
|
|
on demand. This implementation is partially kernel-based to reduce
|
|
overhead in the already-mounted case; this is unlike the BSD
|
|
automounter (amd), which is a pure user space daemon.
|
|
|
|
To use the automounter you need the user-space tools from
|
|
<https://www.kernel.org/pub/linux/daemons/autofs/>; you also want
|
|
to answer Y to "NFS file system support", below.
|
|
|
|
This module is in the process of being renamed from autofs4 to
|
|
autofs. Since autofs is now the only module that provides the
|
|
autofs file system the module is not version 4 specific.
|
|
|
|
The autofs4 module is now built from the source located in
|
|
fs/autofs. The autofs4 directory and its configuration entry
|
|
will be removed two kernel versions from the inclusion of this
|
|
change.
|
|
|
|
Changes that will need to be made should be limited to:
|
|
- source include statments should be changed from autofs_fs4.h to
|
|
autofs_fs.h since these two header files have been merged.
|
|
- user space scripts that manually load autofs4.ko should be
|
|
changed to load autofs.ko. But since the module directory name
|
|
and the module name are the same as the file system name there
|
|
is no need to manually load module.
|
|
- any "alias autofs autofs4" will need to be removed.
|
|
- due to the autofs4 module directory name not being the same as
|
|
its file system name autoloading didn't work properly. Because
|
|
of this kernel configurations would often build the module into
|
|
the kernel. This may have resulted in selinux policies that will
|
|
prevent the autofs module from autoloading and will need to be
|
|
updated.
|
|
|
|
Please configure AUTOFS_FS instead of AUTOFS4_FS from now on.
|
|
|
|
NOTE: Since the modules autofs and autofs4 use the same file system
|
|
type name of "autofs" only one can be built. The "depends"
|
|
above will result in AUTOFS4_FS not appearing in .config for
|
|
any setting of AUTOFS_FS other than n and AUTOFS4_FS will
|
|
appear under the AUTOFS_FS entry otherwise which is intended
|
|
to draw attention to the module rename change.
