Package: dpkg Version: 1.16.10 Severity: wishlist Tags: patch Hi!
We are currently a few folks interested in enabling byte for byte
reproducible builds of Debian packages [1].
In order to achieve this, we need a way to record the environment that
was used to do the initial build. We currently think that the right
place to do so is the `.changes` file.
We can currently easily add new fields there by using the `XC-`
construct in `debian/control`. Unfortunately, `dpkg-genchanges`
does currently not expand all substvars, limiting our abilities to
experiment.
Can you consider applying the following patch that make
`dpkg-genchanges` behave just like `dpkg-gencontrol`?
diff --git a/scripts/dpkg-genchanges.pl b/scripts/dpkg-genchanges.pl
index 0b004c7..13cedd6 100755
--- a/scripts/dpkg-genchanges.pl
+++ b/scripts/dpkg-genchanges.pl
