[Impact]
This bug impacts all cman installations in 12.04. Being unable to update cluster.rng means that one can not verify if cluster.conf is valid.

[Development Fix]
No development version yet.

[Stable Fix]
Patch is a simple patch, affecting only debian/* files. Bug consists of three packaging bugs. Fix makes sure '/var/lib/cluster' is created during installation, it also makes sure 'ccs_update_schema' binary gets installed and adds new dep to cman binary - xsltproc. It's required to properly generate cluster.rng.

[Test Case]
1. Install 12.04 and then install cman package
2. Create file '/tmp/cluster.conf' containing:

<?xml version="1.0"?>
<cluster config_version="1" name="test">
<clusternodes/>
</cluster>

3. Run 'sudo ccs_config_validate -f /tmp/cluster.conf'
4. Expected result:
Configuration validates
(exit code 0)

[Regression Potential]
Regression potential is non-existing since current state of package is unusable.

Original report:

After installing cman and using ccs_tool to create a basic (but valid)
/etc/cluster/cluster.conf, I am unable to run ccs_config_validate:

# ccs_config_validate
Unable to update relaxng schema: /usr/sbin/ccs_config_validate: line 191: ccs_update_schema: command not found
#

I think I have narrowed it down to a missing cluster.rng file:

# ls -al /usr/share/cluster/cluster.rng
lrwxrwxrwx 1 root root 28 Jan 13 17:07 /usr/share/cluster/cluster.rng -> /var/lib/cluster/cluster.rng
# ls -al /var/lib/cluster/cluster.rng
ls: cannot access /var/lib/cluster/cluster.rng: No such file or directory
#
