It is a real shame that you are dropping support for Debian in the future and opting for Ubuntu. Many of us choose our server platforms for the stability of the system, not the cutting edge features. Stability is an area in which Debian has an excellent reputation and Ubuntu has yet to prove themselves.
This is a great project and I look forward to your future releases. I just wish you would maintain a Debian fork... But I understand entirely the limited resources of a project like yours. Do you intend to continue to maintain the Sarge version for any set period of time? Or will support for the Sarge version end when you officially move to the Ubuntu platform?
Thanks again for your incredible work on this fantastic project!
Happy New Year!
