[gentoo-dev] [RFC] @DISTFILE-REDISTRIBUTABLE license group

[Michał Górny]

Hi,

We currently have @BINARY-REDISTRIBUTABLE license group that somewhat
concerns RESTRICT=bindist.  I think it'd be reasonable to introduce
a matching group concerning RESTRICT=mirror.

My proposition would be to add @DISTFILE-REDISTRIBUTABLE group with
the following rules:

- MUST permit redistribution of unmodified distfiles

- MUST NOT require explicit approval (No items from @EULA)

- MAY prohibit redistributing modified distfiles

- MAY restrict the cost of redistribution


Rationale: the main idea is to aid checking for missing
RESTRICT="mirror".  The rules are based on current bindist group but are
more relaxed given the specific use case of our mirrors.  Most notably:

1. It permits licenses that prohibit redistributing modified distfiles. 
In this case, due diligence is required from developers.  If this is
prohibited, they may only add original upstream sources to SRC_URI.

2. It permits restrictions on cost of redistribution, as some upstreams
prohibit selling their products.  While this renders them non-free, it
shouldn't be a problem for our mirrors since we don't expect to sell
stuff there ;-).

Note that while technically there could be a problem with selling, say,
Gentoo CDs with distfiles included, RESTRICT=mirror doesn't cover this
case anyway.


WDYT?
