Hello,
Thanks for the answer.
Is there a way to generate the man pages after downloaded the

Hi, lxc-developers,
I had performed
git clone git://lxc.git.sourceforge.net/gitroot/lxc/lxc
and under doc I don't see any man pages.
for a lxc tar gz I downloaded, they are under doc.
Is there a reason man pages are not in git ?

The original intent of my earlier patch was to avoid different default

we apply these same changes below to lxc-execute please?

I'm not sure if this is relevant to your problem, but last month I sent
a patchset that, among other things, fixes lxc to properly handle cgroup
