Requirements
============

- autofs 5.0.0 requires protocol version 5.00 of the autofs4 kernel
  module (see "Applying the kernel patch" below).

- The LDAP, SASL, and the libxml2 libraries may also be required if
  the LDAP configure options are selected (see "Configure options for
  autofs" below).

How to build and install
========================

To configure, compile, and install the package directly from the
tar distribution, follow these steps.

  1. Make sure you have the latest version of the package available
     from http://www.kernel.org/pub/linux/daemons/autofs/v4.

  2. Type `./configure' to configure the package. You may want to add
     selected configure options. See "Configure options for autofs"
     below.

  3. Build the package by typing `make'

  4. Install the package by typing `make install'.

To build an `rpm' from the tar distribution use:

rpmbuild -tb autofs-5.0.0_beta6.tar.gz

and install the resulting rpm package.

Configure options for autofs
============================

There are several configure options available to add functionality.

--prefix=<root_prefix>
   autofs usually installs in /usr, with the daemon in /usr/sbin,
   the man pages in /usr/man, and the modules in /usr/lib/autofs.
   If you wish to install to a different location use this option.

--with-path=PATH
   Allows the specification of the path to search for utility
   binaries used by autofs during the `configure' process. If
   any of your binaries such as `mount', `mount.cifs' etc. live
   in locations other than /usr/bin:/bin:/usr/sbin:/sbin you
   will need to use this option.
   
--disable-ext-env
   This option disables the ability to the external environment
   to set an external environment variable for substitution.

--disable-mount-locking
   This option disables mount locking which is to prevent corruption
   in /etc/mtab due to multiple concurrent autofs mount commands.

--enable-force-shutdown
   This option enables the use of the USR1 signal to force an
   unconditional unlink umount of all mounts at shutdown.

--enable-ignore-busy
   This option enables the automount to exit ignoring any busy
   mounts upon receiving a TERM signal. automount attempts to
   recover upon startup.

--with-confdir=DIR
  This option allows the specification of the directory that contains
  the autofs configuration file `autofs'. If not given the directories
  `/etc/sysconfig', `/etc/default' and `/etc/conf.d' and checked for
  existence and the first one found is used.

--with-mapdir=PATH
  This option allows the specification of the directory that contains
  autofs mount maps. The directories `/etc/autofs' and `/etc' are
  checked for existence and first one found is used.

--with-hesiod=DIR
  Use this option to enable Hesiod support if your Hesiod library
  isn't installed in /usr/lib with the include files in /usr/include.

--with-openldap=DIR
  Use this To enable LDAP support if your OpenLDAP library isn't
  installed in /usr/lib with the include files in /usr/include.

--with-sasl=DIR
  Use this to enable TLS encrypted connections and LDAP
  authentication using the SASL library. DIR only needs to be
  given if your LDAP and SASL library and include files are
  installed in other than /usr/lib and /usr/include. See
  auto.master(5) for more information about LDAP configuration.

Applying The Kernel Patch
=========================

Patches that can be applied to the kernel are located in the
`patches' directory. If you have installed autofs from an rpm
then they can be found in the packages' doc directory after
install. They consist of a kernel patch for each kernel from
2.6.9 thru 2.6.16 (the patches are in the 2.6.17-rc series so
patching a 2.6.17 or above kernel shouldn't be needed). If
you need a patch for an older 2.6 kernel then post to the
autofs mailing list and ask for one to be done.

To apply one of these patches:

1) change to the root of your kernel source tree.
2) patch the kernel
3) make the kernel
4) Install the kernel as normal.

If you use a packaged kernel then you need to check to see if
the v5 update patch will apply and if it does apply add the
update patch and build your packaged kernel.

For example, Fedora Core 4 kernel package 2.6.11-1.369_FC4
would use the 2.6.12 patch because it applies the 2.6.12 release
candidate revision 6 patch. But the autofs patch doesn't apply
because the rpm also applies a patch somewhere that changes one
area the the patch also changes but this change is not present
in the 2.6.12 release kernel.

On the other hand, Fedora Core 3 kernel 2.6.12-1.1381_FC3
uses the 2.6.12 patch and it applies cleanly because the kernel
doesn't apply a 2.6.13 release candidate patch and there are no
additional patches that clash with the autofs update patch. To
build this kernel with an update patch modify the kernel-2.6.spec
to apply the update patch after all other patches (see example
change below), copy the autofs4-2.6.12-v5-update to the SOURCES
directory of your RPM build tree and us use
`rpmbuild -bb --target=i686 kernel-2.6.spec' in the SPEC directory
of the build tree and install the resulting RPMs.

 # END OF PATCH APPLICATIONS
 
Some Fedora Core kernels have autofs4 bug fix patches, such as
2.6.16-1.2096_FC5. The update patch supersedes all previous patches
so any additional autofs4 patches should be removed and the update
patch added. For example 2.6.16-1.2096_FC5 needs this change:
