Bamboo is producing Debian package, but there is no selection for Debian on the downloads page for Spark. Could be included same as with Openfire.
Actually, Bamboo is failing to produce a deb package, so nothing to put on the web yet.
Debian build is now fixed. Will have to add a download option after the next release.
after 21 line add deb file path/name
after 123 line add new div for deb package (/images/icon_debian.gif)
