Bloody love computers.

Imagine being forbidden from scheduling a shutdown on your very own computer.

What kind of decisions led to this horrid mistake to happen?!

Is there a "user-oriented" version of #systemd that one can use on servers? We have this hardware controls framework that has a tool to graphically see all the device servers running and restart them with a right click → restart. That'd be cool, but for systemd services. #linux

Deal a lot with systemd, so wrote a VSCode extension to observe the state of services.

github.com/gbraad-vscode/vscod

It is at a very early devel; it shows all units and their state, you can start/stop/restart and see status. I would like to do daemon-reloads, auto reloading status/follow, filter for service, sort by state, mask, unmask, etc.

I use this over code serve-web, to help with remote management of services. WDYT?

Edit: new image to be more readable at a small size

The editor shows the content of /etc/systemd/system/code-serveweb@.service. On the right is a tree explorer with the states of all the systemd services; running, stopped, dead, etc. And at the bottom pane the status is shown of the code-serveweb@gbraad.service which runs the editor.

argv minus one

I wonder why systemd-sysv-generator is deprecated for removal.

I mean, it's not particularly consequential—it's a separate program and can therefore be forked if anyone still cares about it—but what's the point of dropping it?

Is it burdensome on the #systemd maintainers somehow? Pretty hard to imagine, seeing as how the LSB specification is frozen and the systemd unit specification is guaranteed backward compatible.

A #systemd thing I just discovered: I was having problems with a service starting on boot before the disk that had the data for it was mounted, and so it'd get upset about missing files and I'd have to manually fix it. I found that systemd has a `RequiresMountsFor=` option, so I can say `RequiresMountsFor=/mnt/path` and the service won't start until that path has been mounted. Simple, handy, and took a surprising amount of searching to find that (for some reason depending on the unit for the mount itself just didn't work.)

在 command line 等 network-online.target 成功後再繼續執行

INN 看起來會在啟動的時候讀 /etc/resolv.conf 決定 DNS server，但我的機器是 PPPoE 取得網路資訊，在 user cron 用下面的方式跑會造成啟動的時候讀到空的 resolv.conf： @reboot ~/bin/rc.news > /dev/null 2>&1 這會導致後續在接受時的 DNS 反解會失敗... 在不改 code 的前提下，第一個想到的方法是直接寫死 DNS servers (像是 168.95.192.1 + 168.95.1.1)，但感覺不太好... 後來想到的解法是改用 systemd 的 Wants= 與 After=，在 ne…

Можно прям средствами сделать чтобы он периодически запускал что-то.
То есть необязательно делать демона, который будет что-то там периодически делать, можно просто прогу, а "периодически" - это уже системд

I once joked about systemd-emacsd. There would be an emacsctl tool to go with it, of course. And no more LISP when simple declarative .INI files are superior and friendlier to modern developers whose laptops might not have a close round bracket key, you know. /usr/lib/systemd/emacsd.conf and /usr/lib/systemd/emacsd.conf.d/ are the future.

But then I once joked about putting an XML parser into process #1; and someone then did that.

Ah.. nothing beats spending 2 hour trying to create a simple #systemd service + timer + bash script to back up an sqlite database every week and it just not working because random permission issues just for selinux to be the culprit. Love how you need another tool to actually understand wtf #SELinux wants from you. #linux
