From: Kay Sievers Date: Thu, 6 Aug 2009 14:16:26 +0000 (+0200) Subject: re-enable failed event tracking X-Git-Tag: 174~862 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=f7c5b04f69e004912327f082be8645b65bb1ff5d;p=systemd re-enable failed event tracking It did not work for the last couple of releases. If RUN{record_failed}+="..." is given, a non-zero execution will mark the event as failed. Recorded failed events can be re-triggered with: udevadm trigger --type=failed The failed tracking _might_ be useful for things which might not be ready to be executed at early bootup, but a bit later when the needed dependencies are available. In many cases though, it indicates that something is used in a way it should not. --- diff --git a/NEWS b/NEWS index b36ace5c..0f41c18b 100644 --- a/NEWS +++ b/NEWS @@ -1,7 +1,15 @@ udev 146 ======== -New keymaps, new modem, hid2hci updated. +Bugfixes. + +The udevadm trigger "--retry-failed" option, which is replaced since quite +a while by "--type=failed" is removed. +The failed tracking was not working at all for a few releases.
