systemd,systemctl: export condition status and show failing condition
$ systemctl --user status hoohoo hoohoo.service Loaded: loaded (/home/zbyszek/.config/systemd/user/hoohoo.service; static) Active: inactive (dead) start condition failed at Tue 2013-06-25 18:08:42 EDT; 1s ago ConditionPathExists=/tmp/hoo was not met Full information is exported over D-Bus: [(condition, trigger, negate, param, state),...] where state is one of "failed" (<0), "untested" (0), "OK" (>0). I've decided to use 0 for "untested", because it might be useful to differentiate different types of failure later on, without breaking compatibility. systemctl shows the failing condition, if there was a non-trigger failing condition, or says "none of the trigger conditions were met", because there're often many trigger conditions, and they must all fail for the condition to fail, so printing them all would consume a lot of space, and bring unnecessary attention to something that is quite low-level.
