Cobbler does work fine with 14.04 LTS in my shop; I have to deploy 15.04 this time because
we are a research institution, and the researchers tell me that 14.04 is too old (packages
too old) for the intended research use... And cannot wait until 16.04 is out next year. So
they want 15.04 deployed.
Thanks,
Will
