first swipe at ctdb spec file

[tridge at samba.org]

Chris,

 > Are there docs on how CTDB works?  I'd like to learn more about it.

There are some docs on wiki.samba.org, such as:

  http://wiki.samba.org/index.php/CTDB_Setup
  http://wiki.samba.org/index.php/CTDB_Project

but they are a bit out of date now. We will be working to improve them
over the next few weeks. CTDB has come a long way in the last month or
so. 

Ronnie started doing some wiki updates over the weekend, but there is
a bit more to do.

Cheers, Tridge
