For the growing user base of phabricator it would be great to make arcanist available as OS package for the major Linux distributions. either as maintained packe of the distribution or to follow the development of archaist more quickly as repository. We have seen the OwnCLoud guys which are distributing the PHP based owncloud application via the hosted build service which creates packages for a number of distributions.

as i side note, while installing arcanist from our local build packages we have a name conflict with the "arc" tool in distribution repositories. you ever have considered to solve the name collision?
