[systemd-devel] systemd-encrypt is a little painful
Hi guys, After making https://www.youtube.com/watch?v=gh3jkIENmAM I'm thinking the install process could be a lot smoother if: somehow systemd could do the initramfs, i.e. take over mkinitcpio's hook role I don't understand why sd-encrypt can't autodiscover the cryto_LUKS root partition. Appending a line like: options rw rd.luks.name=device-UUID=cryptroot root=/dev/mapper/cryptroot is fraught with error and frustration!! Furthermore if you get the above line wrong, the emergency systemd shell appears completely useless. There is the 1m30s timeout that I can never escape, and the emergency shell is confusing and not fit for purpose in the sense of correcting the /dev/mapper/cryptroot address. If these should be new issues or perhaps they are issues already, then do let me know. https://github.com/systemd/systemd/issues?q=sd-encrypt Sidenote: would be cool if a basic en.network could be generated. Perhaps this is all done already in Fedora? haha, I use Arch btw.

[systemd-devel] Formatting Execstart= for readability
Hi there, I maintain a service file with a lot of switches in the ExecStart https://github.com/kaihendry/pingprom/blob/master/prometheus%40.service#L8 I want to almost document each switch ... e.g. -storage.local.retention=8544h # keep data for a year I know inline comments do *not* work in bash IIUC: https://gist.github.com/kaihendry/ff751622c6454176837b1c340b5cfccb And similarly when I try break up lines on something like https://s.natalian.org/2017-08-16/test.service [Service] ExecStart=/usr/bin/curl -X POST -d "fizz=systemd" # some docs -d "some=else" # more docs https://requestb.in/19v8a0m1 It also doesn't work.

It's a Web server header that permits what Web apps can interact with it. https://developer.mozilla.org/en-US/docs/Web/HTTP/Access_control_CORS So a possible API would be: /usr/lib/systemd/systemd-journal-gatewayd --header="Access-Control-Allow-Origin: *" Which would be seen in the output of `curl -I 'http://localhost:19531/entries?boot'`, and the * would allow any Web app no matter where it's hosted to get log events IIUC.

What's the big deal about passing in the DISPLAY environment? I don't see the point of having a non-root user. Trying to keep things as simple as possible to achieve my use case. Which is to start a browser once online. - even worse: it doesn't imply that it is started late in the boot process. Your service may start as early as graphical.target becomes scheduled to start [3] - and that may be well before even basic system setup is finished. Instead, I suggest using a DM with autologin, and then spawn a user service from there. As an alternative, you may want to try working with timer units [2] to activate surf.service a few seconds after X11 is guarenteed to be up, but that would just be a bandaid. Well, if X wasn't up up, I was hoping Restart=always would do the rest. [1]: man systemd.service [2]: man systemd.timer Timers seem like a kluge, just to know when X is ready.

However the naming of my USB mic issue as mentioned at the bottom of http://lists.freedesktop.org/archives/systemd-devel/2013-July/012292.html is still an issue for me. Darkice daemon assumes network and the hw:1,0 (as defined in my /etc/darkice.cfg) device else it bombs out. Can systemd instead perhaps check for hw:1,0 instead for the crazy long device name that changes depending on what port is plugged into?

In systemd ordering deps and requirement deps are truly orthogonal. This is useful in many cases, because sometimes you just want to pull something else in, but not imply any ordering, sometimes you want to order without actually pulling it in, and often you want to do both. Of course, not all deps make sense in all combinations, but I think it's easy enough to grasp. What happens in the range of error cases when a user puts a Wants= line under the (wrong) [Install] heading? I tried it and network-online.target was loaded inactive dead, so it failed IIUC. No warning that Wants= line is in the wrong place. This sucks quite a lot imo. Wouldn't it be simpler if systemd ignored the headings? Anyway, it's just a comment. I am still trying to figure darkice starting out. I figure you could try this with a service like the following (untested): [Unit] Before=network-online.target [Service] ExecStart=/usr/bin/ping -nq 8.8.8.8 -w 60 -c 1 Type=oneshot StandardOutput=null [Install] WantedBy=network-online.target Then, install and enable this service, and pull in network-online.target from the service that you want to wait for the network to be around. I enabled the above as pingtest.service and added Wants=network-online.target under the [Unit] heading in darkice.service. Still I don't understand how pingtest.service can fail here with exit 2 and even more confusingly network-online.target is reached!? http://ix.io/6Nv This will timeout after 60 seconds. Isn't this better controlled by systemd itself? And not be a command line switch in the exec? It's hacky, generates awful traffic, and has quite some latency, but it should do what you asked for... Awful traffic? One successful ping and we continue IIUC. A lot of routers IIUC do a heart beat type ping to ensure it's up. And if not it would switch to another route or something.

Thanks this fixes the first scenario: http://sprunge.us/LiQF I must say needing After BindsTo is a bit confusing. I also don't see the need for different sections. Never quite know under which heading a stanza should go. The timestamp looks weird. Does the device have no RTC or so? no RTC, so does that mess up the retry interval code I wonder? Because I don't mind if systemd just retries it every so often. But that doesn't work. :/ Not sure I like the suggestions here: http://www.freedesktop.org/wiki/Software/systemd/NetworkTarget/ I despise NetworkManager. Hasn't someone written a simple service that say pings 8.8.8.8 and if that's OK, says the network is up? That's how even enterprise routers work. ___ systemd-devel mailing list systemd-devel@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/systemd-devel

Indeed it does. Though how do I listen on journalctl for *future events*? `journalctl -f -b MESSAGE='Lid closed.' MESSAGE='Lid opened.' -o export | grep SOURCE_REALTIME_TIMESTAMP` annoyingly shows past events. Mayyybe tweaking --since, but that easily throws this `Failed to get realtime timestamp: Cannot assign requested address` error.

Thanks! Any ideas how to stream out only new events? Ideally both open close? Many thanks, ___ systemd-devel mailing list systemd-devel@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/systemd-devel
[systemd-devel] Definitive place for powertop tunables?
Hi there, I would normally put these `powertop -html` tunables in rc.local: http://s.natalian.org/2012-11-19/1353291487_1366x768.png Is http://0pointer.de/public/systemd-man/tmpfiles.d.html the right place? If so powertop could do with some patches to help create the file, one would think.

Re: [systemd-devel] cgroup use case for preventing a system lock up if say a browser exhausts memory
On 12 November 2012 19:35, Colin Guthrie gm...@colin.guthr.ie wrote: When launching firefox becomes a user unit, then it will be contained within it's own cgroup and can have resource limits imposed with relative ease. Thanks Colin for your reply. I'm interested in a general systemd framework example of a system process resource limited. Do you have one you can point me to? What's important for me here, since this can run on machines with varying amount of memory that it's basically restarted when it's nearing memory exhaustion. Tbh I think the OOM killer should just do this, but I gather it's more complicated than that.

[systemd-devel] cgroup use case for preventing a system lock up if say a browser exhausts memory
Hi there, I hope this is the right forum for a systemd question, to address a particular problem I'm trying to solve. Problem is I've found Firefox (for example, this probably can be extrapolated to any browser) to lock up machines when memory is exhausted. Ideally when the browser hits a certain limit (only 5% of free RAM left), Firefox is killed and restarted, to solve my particular kiosk use case. https://github.com/Webconverger/webc/issues/83 I've looked and tested varying unsatisfactory solutions and since I'm an Archlinux user who has been put onto systemd (tbh I'm impressed), I was eager to know if systemd can help. I can't help but notice how busy my `mount` looks now: http://ix.io/3nt I've done a quick couple of searches trying to find how to use cgroups for controlling limits with systemd and I'm still in the dark. I was half expecting a service file example to have a resource limit stanza. Am I looking in the right place?
