[lxc-users] Mounted /proc entries empty

[Ben Green]

Hi all,

sad I didn't get any response at all, but I fixed my problem anyway.  
It turns out that lxcfs was unable to mount it's fuse mount on  
/var/lib/lxcfs because a file had ended up there, and fuse won't mount  
if it finds a non-empty directory. Once I cleared out that directory  
and restarted lxcfs it all worked fine.

Cheers,
Ben
