Cobalt RaQ4 was laying around collecting dust so I decided to give it a second chance. Guys from OS Office (http://www.osoffice.co.uk) put together Strongbolt – excellent Linux distribution based on CentOS with Cobalt RaQ support.
I wanted to use Cobalt RaQ4 to test highly available and load balanced cluster configuration. However current Strongbolt kernel 2.6.16i586 doesn’t have IP virtual server support and had to be recompiled.
