Hi,

as soon as I enable network namespaces with touch
/etc/vservers/VSNAME/spaces/net, /proc/net/ within the vserver is empty.
This again breaks ifconfig and dhclient.
ip a l only shows 'lo'.
Adding more entries to vprocunhide doesn't make any difference.
/proc/self/net is just as empty as /proc/net.
