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.

Is Systemd that bad afterall? (sopuli.xyz)

SystemD is blamed for long boot times and being heavy and bloated on resources. I tried OpenRC and Runit on real hardware (Ryzen 5000-series laptop) for week each and saw only 1 second faster boot time.

I'm old enough to remember plymouth.service (graphical image) being the most slowest service on boot in Ubuntu 16.04 and 18.04. But I don't see that as an issue anymore. I don't have a graphical systemD boot on my Arch but I installed Fedora Sericea and it actually boots faster than my Arch despite the plymouth (or whatever they call it nowadays).

My 2 questions:

Is the current SystemD rant derived from years ago (while they've improved a lot)?
Should Linux community rant about bigger problems such as Wayland related things not ready for current needs of normies?

if you have a java application and you want to dynamically manage java parameters and application parameters

If you mean you want to auto-detect appropriate values that is no more complicated than the init script was before. You just call that wrapper script.

If you mean you want to turn those on and off as part of your local configuration that is actually quite easy with drop-ins in systemd, much easier than modifying the init script and then having issues with the package overwriting your script with a new copy.

I don't deny that systemd is easier than SysV. I say that on complex configurations it is not slightly simpler. Moreover, what I could do just in the sysV script, I now have to divide by tmpfiles.d and systemd. And sometimes even include processing both there and there, because depending on the version systemd has different behavior with parameters LogsDirectory= and RuntimeDirectory=. As a result, the dependence on the system has not completely disappeared for the package maintainer. Although of course there are a little less problems with systemd.

On other side as a user, I don't really like to guess exactly how a folder was created in /run, via tmpfiles or via systemd.

UPD: On SysV I have one complex, heavy script. Now I have the systemd service, the tmpfiles configuration, the /etc/conf.d parameters file and there is still a shell script to run. But if user wants reconfig something he need look 4 files instead one.
