Release 2017.4

Things are starting to ramp up notably for rpm-ostree.  This
release fixes a number of bugs; for example, installing `mock` on
the host now works.
Issue: https://github.com/projectatomic/rpm-ostree/issues/671

We also fixed a regression related to GPG from 2017.3 that affects
COPR notably.

There’s an effort in Fedora called “Modularity” that effectively gives allows multiple lifecycles for different components.

Today (and since the start), Fedora Atomic Host is Fedora - we have just added another build process at the end of the "Everything" build process (and the same is true of the registry.fedoraproject.org/fedora container). There's a lot of benefits to that; any security fixes to e.g. glibc or openssl automatically

Server side (just informational)

You don't have to do any of this; I'm just showing what I did. Skim this and skip to the Client section below.

rpm-ostree cancel

It's interesting that most package management tools are command lines (as opposed to daemons with a client, or shared libraries). Instead there's e.g. PackageKit or apt-daemon which layer on top.

Being a command line is good for a lot of scenarios; for example docker build and RUN yum -y .... But ironically, managing the host system is really where you want a daemon by default.
