Yes, it is. And for the most part, container creation templates should
know what sort of distro, and hence init, they are setting up, so they
can add the right lxc.signal.stop. But it *is* too bad that there is no
way really to query "hey, for this init that's running in this container,
what *should* I send it?" I suspect that's where some users get annoyed.
If you're creating and destroying a lot containers with a lot if
different distros, I can see where having to guess this for yourself can
be a bit of a blocker. So since you can't query, a convention would be
nice. But that ship too has sailed.
