The tar.gz package is compatible with RedHat and Debian OS based, CollectNode is a portable software, so all the requirements are already packaged (except the samba-client package, only required if you are going to work with Windows systems.)
so far, you can download the tar.gz or rpm package, a .deb package will come eventually. CollectNode doesn't required any client installation, so is not required to install the client package as mcollective requires, and any way, collectNode is very focused on the report, making very useful to get a global view about you want to know easily.
