* unit: drop Before=sysinit.target from systemd-random-seed.serviceYu Watanabe2019-08-051-1/+1
| | | | | | | | | | | | | Follow-up for 26ded55709947d936634f1de0f43dcf88f594621. The commit says, > Note that with this change sysinit.target (and thus early boot) is NOT systematically delayed until the entropy pool is initialized, But the dependency was not dropped. This was found by David Seifert (@SoapGentoo).
* random-seed: rework systemd-random-seed.service substantiallyLennart Poettering2019-07-251-1/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This makes two major changes to the way systemd-random-seed operates: 1. We now optionally credit entropy if this is configured (via an env var). Previously we never would do that, with this change we still don't by default, but it's possible to enable this if people acknowledge that they shouldn't replicate an image with a contained random seed to multiple systems. Note that in this patch crediting entropy is a boolean thing (unlike in previous attempts such as #1062), where only a relative amount of bits was credited. The simpler scheme implemented here should be OK though as the random seeds saved to disk are now written only with data from the kernel's entropy pool retrieved after the pool is fully initialized. Specifically: 2. This makes systemd-random-seed.service a synchronization point for kernel entropy pool initialization. It was already used like this, for example by systemd-cryptsetup-generator's /dev/urandom passphrase handling, with this change it explicitly operates like that (at least systems which provide getrandom(), where we can support this). This means services that rely on an initialized random pool should now place After=systemd-random-seed.service and everything should be fine. Note that with this change sysinit.target (and thus early boot) is NOT systematically delayed until the entropy pool is initialized, i.e. regular services need to add explicit ordering deps on this service if they require an initialized random pool. Fixes: #4271 Replaces: #10621 #4513

* units: do not start load-random-seed in containers (#3941)Zbigniew Jędrzejewski-Szmek2016-08-131-0/+1
| | | | | Random numbers are provided by the host kernel, we don't need to do anything. https://bugzilla.redhat.com/show_bug.cgi?id=1329124
* units: specify timeouts for more oneshot servicesZbigniew Jędrzejewski-Szmek2015-04-281-0/+1
| | | | | | | | | Even trivial service occasionally get stuck, for example when there's a problem with the journal. There's nothing more annoying that looking at the cylon eye for a job with an infinite timeout. Use standard 90s for jobs that do some work, and 30s for those which should be almost instantenous.

* units: rework systemd-random-seed-{load,save}.service to be a single serviceLennart Poettering2013-05-151-0/+21
That way ordering it with MountsRequiredFor= works properly, as this no longer results in mount units start requests to be added to the shutdown transaction that conflict with stop requests for the same unit.
