-LVM2 installation
-=================
+Installation
+============
 
-1) Install device-mapper
-
-   Ensure the device-mapper has been installed on the machine.
-
-   The device-mapper should be in the kernel (look for 'device-mapper'
-   messages in the kernel logs) and /usr/include/libdevmapper.h 
-   and libdevmapper.so should be present.
-
-   The device-mapper is available from:
-     ftp://ftp.sistina.com/pub/LVM2/device-mapper/
-
-
-2) Generate custom makefiles.
+1) Generate custom makefiles.
 
    Run the 'configure' script from the top directory.
 
-   If you wish to use the built-in LVM2 shell and have GNU readline 
-   installed (http://www.gnu.org/directory/readline.html) use:
-     ./configure --enable-readline
-
    If you don't want to include the LVM1 backwards-compatibility code use:
      ./configure --with-lvm1=none 
 
    To separate the LVM1 support into a shared library loaded by lvm.conf use:
      ./configure --with-lvm1=shared
 
+   Use ./configure --help to see other options.
 
-3) Build and install LVM2.
+2) Build and install.
 
-   Run 'make install' from the top directory.
+   Run 'make' from the top directory to build everything you configured.
+   Run 'make install' to build and install everything you configured.
 
+   If you only want the device-mapper libraries and tools use
+   'make device-mapper' or 'make install_device-mapper'.
 
-4) Create a configuration file
+3) If using LVM2, create a configuration file.
 
    The tools will work fine without a configuration file being
    present, but you ought to review the example file in doc/example.conf.
-   For example, specifying the devices that LVM2 is to use can
-   make the tools run more efficiently - and avoid scanning /dev/cdrom!
 
 Please also refer to the WHATS_NEW file and the manual pages for the 
 individual commands.

-LVM2 requires the device-mapper kernel module (dm-mod).  This is
-available as a kernel patch for 2.4 (in kernel-patch-device-mapper), and
-is distributed with linux 2.5 and above.  The LVM1 kernel module (lvm-mod)
-will not work with lvm2 packages.  dm-mod and lvm-mod may both be loaded
-in the kernel at the same time with no problems.  Without dm-mod, this

-Description: The Linux Logical Volume Manager
- This is LVM2, the rewrite of The Linux Logical Volume Manager.  LVM
- supports enterprise level volume management of disk and disk subsystems
- by grouping arbitrary disks into volume groups. The total capacity of
- volume groups can be allocated to logical volumes, which are accessed as
- regular block devices.
- .
- LVM2 is currently stable, but has some unimplemented features (most notably,
- pvmove and e2fsadm).  It is not yet recommended for production use.  It is
- backwards-compatible with LVM1 (lvm10), and requires Linux kernel 2.4.
