Well depends on how you look at it.

I do have a build environment for a number of different services. I moved most of the dev environments to virtual machines though. > Besides - I don't see a big deal.

I understand your argument. It seems strange that you would be making the argument given you are one of the people who likes to get their hands dirty. :) I just think there has to be a better way to do it, sans moving to a bsd style kernel... :) _______________________________________________ arm mailing list arm@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/arm
