Systemd: Hidden Gems for a Better Linux
Systemd: Hidden Gems for a Better Linux
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 d...
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. :)

Very interesting article with lots of links that I'm sure to revisit often. I use Linux daily and was not aware of all the possibilities that systemd has to offer.
Some of the cruft I use nowadays to manage Linux machines can be optimized by simply moving over to the systemd equivalent. Of particular interest to me are: triggers, timers, file monitoring, and ntp.
Thank you. NTP and DNS are the easiest to get into. Simply enable the services and move on.
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=noYour 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.confhttps://www.freedesktop.org/software/systemd/man/systemd.network.html#[DHCPv4] Section Options
Oh yes 😆 hur der I didn't read da manual. Why is it in a tread about systemd people lower themselves to this kind of response!
And no I had read the manual and it's down to how systemd handles IPv6 and rather than disable that I chose to disable resolved and return back to openresolv. Which works and is perfectly fine.
not even that for ntp you just set it with timedatectl
