From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Porting systemd to musl libc-powered Linux (catfox.life)

submitted 2 months ago by [email protected] to c/[email protected]

I have completed an initial new port of systemd to musl. This patch set does not share much in common with the existing OpenEmbedded patchset. I wanted to make a fully updated patch series targeting more current releases of systemd and musl, taking advantage of the latest features and updates in both. I also took a focus on writing patches that could be sent for consideration of inclusion upstream.

The final result is a system that appears to be surprisingly reliable considering the newness of the port, and very fast to boot.

...

And that is how I became the first person alive to see systemd passing its entire test suite on a big-endian 64-bit PowerPC musl libc system.

...

While the system works really well, and boots in 1/3rd the time of OpenRC on the same system, it isn’t ready for prime time just yet.

...

There aren’t any service unit files written or packaged yet, other than OpenSSH and utmps. We are working with our sponsor on an effort to add -systemd split packages to any of the packages with -openrc splits. We should be able to rely on upstream units where present, and lean on Gentoo and Fedora’s systemd experts to have good base files to reference when needed. I’ve already landed support for this in abuild.

It boots faster than openRC (which is painfully slow). But runit is a lot faster than systemd, and there are init systems even faster than runit. And they all already work with musl. There is even dinit system specifically designed for containers.

What is the name of the dinit system designed for containers?
