[PATCH] gnu: Add haveged.

[PATCH] gnu: Add haveged.

[Tobias Geerinckx-Rice]

* gnu/packages/linux.scm (haveged): New variable.

Hullo Guix,

- A package for haveged, for those who trust it.

- A question about licencing, for those with more knowledge than me.

How'd I best encode these (presumably FSDG-compliant) licences?

Kind regards,

I would use 'non-copyleft'. There's an example in the libbsd package and
several others.

Otherwise, the package looks good to me, thanks!

That's the one. I've added:

  (license:non-copyleft "file://nist/mconf.h")
  (license:non-copyleft "file://nist/packtest.h")
  ...

but many packages — not all — also like to add a "See <filename> in the
distribution." Looking at guix/licenses.scm, this seems a bit redundant
to me. No?

Thanks! I'll push (\o/) in a day or so if no-one else comments.

Kind regards,

I think it's a matter of judgement. Sometimes it makes sense, sometimes
not. The important thing is to say where the license text is.

Judged and pushed (without the apparent duplication).

Thanks,
