Systemd is incredibly versatile and most people, including myself, are unaware of its full potential. Despite its usefulness, it is often overlooked due to controversy and the current state of things when it comes to software development. Begin today your journey thought Systemd's capabilities and discover how to efficiently manage systems with fewer processes than traditionally used.

After a few conversations with people on Lemmy and other places it became clear to me that most aren’t aware of what it can do and how much more robust it is compared to the usual “jankiness” we’re used to.

In this article I highlight less known features and give out a few practice examples on how to leverage Systemd to remove tons of redundant packages and processes.

And yes, Systemd does containers. :)

    I stopped using resolved as it tends to ignore what I tell it to do and still grab DNS from the router which I don’t want and can’t disable on the proprietary router.

    openresolv/Resolveconf was never broken in the first place so I’m not sure what systemd was trying to fix with this.

      That’s most likely because… you didn’t read the manual! :D

      FallbackDNS= A space-separated list of IPv4 and IPv6 addresses to use as the fallback DNS servers. Please see DNS= for acceptable format of addresses. Any per-link DNS servers obtained from systemd-networkd.service(8) take precedence over this setting, as do any servers set via DNS= above or /etc/resolv.conf.

      Assuming your network is DHCP, edit your config eg. /etc/systemd/network/10-eth0.network:

      [DHCPv4]
UseNTP=no
UseDNS=no
UseHostname=no

      Your system will not pick NTP and DNS servers and also ignore the hostname provided by the router. Also make sure you ln -sf /run/systemd/resolve/resolv.conf /etc/resolv.conf
