Support system-level profiles

[technomancy]

This would be useful for systems like Debian that want to offer a system-wide repository mirror.

I see that these profiles are merged in with plain merge. So if you put {:user { whatever }} in /etc/leiningen/profiles.clj, then all of whatever is nuked by the existence of a :user profile in ~/.lein/profiles.clj, without warning.

Is that intended?

[hypirion]

@djpowell Yes, that is the intent. The priority is default profiles, system profiles, user profiles, project profiles and then finally project map profiles (the later, the better).

[djpowell]

So, for the use-case described in the original issue; if you define a system-wide :repositories mirror for :user at system level, then the mere existence of :user at the user profile, will deactivate that mirror, even if there is no :repositories key at user level?

Given that user-level :user will almost always exist, this doesn't seem to help with the original use-case?

[technomancy]

Yeah, so this was requested by the guy doing Debian packaging, but I think it's not really useful unless we add another activated-by-default profile. Maybe :system.
