[PKG-Openstack-devel] Bug#835179: zaqar: FTBFS with eatmydata (build hangs)

[Santiago Vila]

Package: src:zaqar
Version: 2.0.0-2
Severity: wishlist

Dear maintainer:

I tried to build this package in stretch with "dpkg-buildpackage -A"
(which is what the "Arch: all" autobuilder would do to build it)
but it failed:

The build was made with eatmydata. When I don't use eatmydata, it builds ok
(but it takes a lot more time to build).

Can you confirm that eatmydata is the reason for the failures
and / or forward this upstream?

I'm currently checking that "dpkg-buildpackage -A" always work, and
the ability to use eatmydata is a real time and disk I/O saver.

Thanks.
