How is this for a readme:

OHSM is a Open Hierarchical Storage Management that includes both kernel and user
space components.  The kernel aspect for now is composed of a EXT2 patch and a ohsm
module.

A whitepaper describing it can be found at <...>

The current release ohsm 1.1.1 only supports the 2.6.30 kernel.  The kernel needs to
be patched, so you need to download a vanilla copy from lkml.org for example.

One option is to install it in /usr/src.  This can be done by downloading the tar.bz
file to your home download directory, then as root copying it to /usr/src, then
expanding it via tar -xjf linux-2.6.30.tar.bz2

For background information on basic kernel downloading and compiling see Robert Day's
article at:
<http://linux.com/learn/linux-training/29812-the-kernel-newbie-corner-building-and-running-a-new-kernel>

Once you have the kernel downloaded and compiled you are ready to try and boot from
it.  The ohsm compile scripts assume you are running from the 2.6.30 kernel you will
be patching and working with.

So go ahead and reboot to the new vanilla kernel.

Once you have that working you are ready to patch in the ext2 ohsm changes.  (I don't
see this in ohsm 1.1.1.  Where should a new user find it?)

Patch in the ext2 patch via:


You are now ready to start building ohsm!

To compile it you need device-mapper-devel and libxml2-devel installed.  This will
provide libdevmapper.h and the necessary xml programs and headers.

Once you have those installed it is the standard:

./configure
make
make install

sequence

What could be simpler?

Yes, I think this is enough information to start with.
