Our spec file is non-deterministic if you have this in your ~/.rpmmacros:
%_without_udev 1
because it then depends on whether you have systemd-devel installed
rather than being explicitly stated in the spec file.
[At this point, I'm sending the series to get the review started on the
two trivial parts; I'm still working on patch 3, including coming up with
a formula for proving that the unpatched build was non-deterministic,
rather than just my claim above]

Thanks; fixed (actually, reworded):
build: use --with-systemd-daemon as configure option

Thanks; pushed. (Missed rc2, but that's no real loss).

New subject: [libvirt] [PATCH 2/3] spec: explicitly avoid bhyve on Linux
Generally, we try to make the spec file tweakable via user
variables, so that they can select a different subset of sub-rpms
to build. We also try to explicitly list all driver config
options, rather than leaving the chance that the rpm build may be
non-deterministic based on what the user had installed locally.
But in the case of the recent bhyve hypervisor driver, there is
no port of bhyve to Linux, so it is easier to just blindly
disable it for now. If someone ever does try to port bhyve to
Fedora, we can make the spec file conditional at that point.
* libvirt.spec.in (%configure): Don't try to build bhyve.

New subject: [libvirt] [PATCH 2.5/3] spec: require device-mapper-devel for storage-disk
On Fedora 20, with the following in my ~/.rpmmacros:
%_without_udev 1
%_without_storage_mpath 1
and with device-mapper-devel uninstalled, 'make rpm' fails with:
checking for libdevmapper.h... no
configure: error: You must install device-mapper-devel/libdevmapper >= 1.0.0 to compile
libvirt
error: Bad exit status from /var/tmp/rpm-tmp.Wo9pOG (%build)
The fix is to match the logic in configure.ac on when devmapper
is required (for both mpath and storage). While at it, rbd
storage is not dependent on mpath.
* libvirt.spec.in (BuildRequires): Fix build when mpath is
disabled.

New subject: [libvirt] [PATCH 3/3] spec: make systemd_daemon usage configurable
On Fedora 20, I added this to my '~/.rpmmacros':
%_without_udev 1
%_without_storage_mpath 1
%_without_storage_disk 1
and uninstalled systemd-devel (which also removed device-mapper-devel).
Then I ran 'make rpm', and inspected the results:
$ ldd ~/rpmbuild/BUILD/libvirt-1.2.2/daemon/.libs/libvirtd | grep syst
$
Then I reinstalled systemd-devel, where I now see:
$ ldd ~/rpmbuild/BUILD/libvirt-1.2.2/daemon/.libs/libvirtd | grep syst
libsystemd-daemon.so.0 => /lib64/libsystemd-daemon.so.0 (0x00007ffb858ba000)
$
Oops - the build is non-deterministic, where the final binary
depends on my build environment. The fix is to require
systemd-devel in all situations where the code base uses it.
Now ~/.rpmmacros can contain "%define _without_systemd_daemon 1"
to explicitly disable use of the library, but the library is now
a strict build requirement for normal builds; if systemd-devel
is not installed, the user now gets an up-front warning:
$ rpmbuild -ta libvirt-1.2.2.tar.gz
error: Failed build dependencies:
systemd-devel is needed by libvirt-1.2.2-1.fc20.x86_64
* libvirt.spec.in (with_systemd_daemon): New variable.
(BuildRequires): Require systemd-devel for more than just udev.
