I current have a simple server running RedHat, and wanting to switch to FreeBSD as I think that FreeBSD would offer better platform as a server in stability and security patches as such. (Am I correct here or what ? :-) I am doing all my research just to make sure I am making the correct decision here. And this one about the single user mode is really making me cold feet at the moment :-) I will contact data centres just to make sure that they have all the facility needed to boot it into single user mode. Thanks again Oh, btw, I have a quick scan on your personal page, very impress that you are helping to maintain the servers. Would my choice of FreeBSD over RedHat be correct in this instance for a webserver do you think?
