Bug#1032409: esda: please make the build reproducible

[Chris Lamb]

Source: esda
Version: 2.4.3-2
Severity: wishlist
Tags: patch
User: reproducible-bui...@lists.alioth.debian.org
Usertags: buildpath filesystem

Hi,

Whilst working on the Reproducible Builds effort [0] we noticed that
esda could not be built reproducibly.

There were actually two issues I needed to address:

 * The documentation embedded the full build path, ironically because
   esda was incorrectly passing a directory to env.doc2path, a
   path-related utility. This second parameter is actually a boolean
   argument, and the attempt to make the path relative was actually
   being interpreted as a boolean — specifically, that it should be an
   absolute pathname.

 * debian/rules calls out to jdupes, but this utility cleans up
   duplicates depending on the underlying filesystem order.

Patch attached for both issues.
