+ Before starting a unit
+ verify that the specified condition is
+ true. With
+ ConditionPathExists=
+ a file existance condition can be
+ checked before a unit is started. If
+ the specified absolute path name does
+ not exist startup of a unit will not
+ actually happen, however the unit is
+ still useful for ordering purposes in
+ this case. The condition is checked at
+ the time the queued start job is to be
+ executed. If the absolute path name
+ passed to
+ ConditionPathExists=
+ is prefixed with an exclamation mark
+ (!), the test is negated, and the unit
+ only started if the path does not
+ exist. Similarly
+ ConditionKernelCommandLine=
+ may be used to check whether a
+ specific kernel command line option is
+ set (or if prefixed with the
+ exclamation mark unset). The argument
+ must either be a single word, or an
+ assignment (i.e. two words, seperated
+ by the equality sign). In the former
+ case the kernel command line is search
+ for the word appearing as is, or as
+ left hand side of an assignment. In
+ the latter case the exact assignment
+ is looked for with right and left hand
+ side matching. If multiple conditions
+ are specified the unit will be
+ executed iff at least one of them
+ apply (i.e. a logical OR is
+ applied).
