Bug#963466: qemu-system-data: Use reproducible timestamps in openbios roms

[Vagrant Cascadian]

Package: qemu-system-data
Version: 1:5.0-5
Severity: normal
Tags: patch
User: reproducible-builds at lists.alioth.debian.org
Usertags: timestamps
X-Debbugs-Cc: reproducible-bugs at lists.alioth.debian.org

The various openbios roms include time and date information embedded in
the binary.

The attached patch uses the SOURCE_DATE_EPOCH environment variable,
which is exported by dpkg-buildpackage, to set the date to a consistant
value between builds. It relies on features of GNU date in order to keep
the patch simple, though that may prevent it from being upstreamable.

Thanks for maintaining qemu!


live well,
  vagrant
