[Lxc-users] newbie question: why all the lxc must be in /etc/lxc?

[fpemud]

sorry I don't know if it is already been asked. (where to seach?)

"lxc-create -n" creates new lxc in /etc/lxc, it's ok.

but "lxc-start -n" also needs the lxc in /etc/lxc, it's too restrictive.
I want to freely put my lxc in any directory of course.

is there any technical reason? or is it a missing feature?
is there any workaround?
