Your'e completely right, that 'thread-save' wasn't the right term. And of corse, booting a bunch of containers by sequential calls of lxc-start will take not significant more time than doing it in parallel -- because most of the lauch time is spend by the Linux bootstrapping.

But I want to know it for another reason: If I going to write automated scripts to lauch some containers, they might be called "at the same time" (in terms of the lauch time of lxc before forking the init). And therefore I ask if I have to avoid a possible race condition by any kind of semaphore or is it safe to lauch it more than one time.
