Hello,

I've just gave lxc-5 a test and all my unprivileged containers fail to
start because they cannot mount a directory any more.
Now, in the (online) release notes I have not found any mount related
changes, so I am wondering, what I may be missing?
Downgrading makes everything work again.

any ideas where I might start looking?

Thanks

Ede
