systemd is a suite of basic building blocks for a Linux system. It provides a system and service manager that runs as PID 1 and starts the rest of the system. systemd provides aggressive parallelization capabilities, uses socket and D-Bus activation for starting services, offers on-demand starting of daemons, keeps track of processes using Linux control groups, supports snapshotting and restoring of the system state, maintains mount and automount points and implements an elaborate transactional dependency-based service control logic. systemd supports SysV and LSB init scripts and works as a replacement for sysvinit.

The Biggest Myths of systemd

Since we first proposed systemd for inclusion in the distributions it has been frequently discussed in many forums, mailing lists and conferences. In these discussions one can often hear certain myths about systemd, that are repeated over and over again, but certainly don’t gain any truth by constant repetition. Let’s take the time to debunk a few of them.

Revisiting How We Put Together Linux Systems

In a previous blog story I discussed
Factory Reset, Stateless Systems, Reproducible Systems & Verifiable Systems,
I now want to take the opportunity to explain a bit where we want to
take this with
systemd in the
longer run, and what we want to build out of it. This is going to be a
longer story, so better grab a cold bottle of
Club Mate before you start

Traditional Linux distributions are built around packaging systems
like RPM or dpkg, and an organization model where upstream developers
and downstream packagers are relatively clearly separated: an upstream
developer writes code, and puts it somewhere online, in a tarball. A
packager than grabs it and turns it into RPMs/DEBs. The user then
grabs these RPMs/DEBs and installs them locally on the system. For a
variety of uses this is a fantastic scheme: users have a large
selection of readily packaged software available, in mostly uniform
packaging, from a single source they can trust. In this scheme the
distribution vets all software it packages, and as long as the user
trusts the distribution all should be good. The distribution takes the
responsibility of ensuring the software is not malicious, of timely
fixing security problems and helping the user if something is wrong.

CoreOS is building a container runtime, Rocket

We thought Docker would become a simple unit that we can all agree on.

Unfortunately, a simple re-usable component is not how things are playing out. Docker now is building tools for launching cloud servers, systems for clustering, and a wide range of functions: building images, running images, uploading, downloading, and eventually even overlay networking, all compiled into one monolithic binary running primarily as root on your server. The standard container manifesto was removed. We should stop talking about Docker containers, and start talking about the Docker Platform. It is not becoming the simple composable building block we had envisioned.

Fedora 21 Is Coming In Just Two Days With Big Improvements

Fedora 21 is the first release of the Fedora.Next initiative that separates Fedora out into three products: Fedora Cloud, Fedora Server, and Fedora Workstation. These new Fedora “products” are fairly self explanatory and it’s the Fedora 21 Workstation that most users will be after who want Fedora as a desktop operating system.

Fedora 21 is due out in a few days and as such I’ve been busy extensively testing and benchmarking this first Fedora Linux update in a year. To not much surprise given the close package versions to Ubuntu 14.10, Fedora 21 isn’t performing very differently from the Ubuntu Utopic Unicorn.
