I really want to do it, and my gentoo blog really needs some new content, but I just don't have tim= e. I'm working everyday until 22:00 and my 7months son also needs me, so I rea= lly try to be everywhere. I'm pushing Gentoo, because it can be tailored automatically for a lot of projects. >From small devices to a cluster. The initial go is very hard with steep curve, but what I aim for is the ease of use and replication when problem strike or wh= en moving to new project. As for Catalyst, I'll try to post my conclusion about this tool for our use= . I'll try to document more what I'm doing. Regards, Kfir
