What is systemd and why does it matter to Linux users?

In today's open source roundup: What is systemd and why should Linux users care about it? Plus: An infographic guide to understanding Debian, and two ancient Linux watches from IBM

The systemd controversy seems to be a never ending saga among Linux users. But just what the heck is systemd and why should anybody care? ZDNet has an article this morning that provides an overview of systemd, and it includes some comments by Linus Torvalds and other Linux leaders.

According to ZDNet:

Systemd provides a standard process for controlling what programs run when a Linux system boots up. While systemd is compatible with SysV and Linux Standard Base (LSB) init scripts, systemd is meant to be a drop-in replacement for these older ways of getting a Linux system running.

Systemd, which was created by Red Hat's Lennart Poettering and Kay Sievers, does more than start the core programs running. It also starts a journal of system activity, the network stack, a cron-style job scheduler, user logins, and many other jobs. That may sound good to you, but some developers hate it.

ZDNet did a good job presenting systemd for those who might be unfamiliar with it, and there's no doubt that the controversy surrounding it is going to continue for the foreseeable future.

If you want more info about systemd, you can get it on Wikipedia's overview article. You can also drop by the systemd site for links to social media, mailing lists, and lots of other helpful resources.

Understanding Debian infographic

I bumped into an infographic this morning that is packed with information about Debian. It's a very large image, so be sure to click through to the original source. The version I have included below is quite tiny by comparison.
