cobbler check doesn't properly detect that BIND is available on Fedora 11. It runs "named --help" and it searches in its stdout for "unknown option". On Fedora 11, this is printed on stderr, not on stdout.
What I would like to propose is to run "named -v" which prints to stdout something like "BIND 9.6.1-P1-RedHat-9.6.1-6.P1.fc11". I think that it's saner to use an option that's actually supported, than one that is not. Unfortunately I don't have access to a RHEL system, so I don't know if this idea would work on RHEL, too. I'm waiting for your feedback and opinions regarding this.
Thank you, Cristian
