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.

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:

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

We'd probably need to qualify this with "bad compared to what". I can't complain, as it does its job, and I've been able to tweak what I needed to. As I don't tinker with it every week, I keep a sticky note rolled up on my desktop, or I quickly use 'cheat systemd' to remember some key examples.

I was getting really long start up time earlier this year (like 19 mins before the desktop was fully responding) and after trying everything else I tried ditching BTRFS and reverting my /home drive back to ext4. Turns out BTRFS start and checks was killing my boot times. Now, as fast as anything.

The following have been my saviours though in identifying boot times: journalctl -b -p err systemd-analyze blame --user systemd-analyze blame
