[Lxc-users] Linux Mint and cgroups on /sys/fs/cgroup or /dev/cgroup/cpu

[arjan]

Hi,

This seems a list of lxc users only right? Anybody reading and replying 
here that actually knows about the nitty-gritty of lxc?

To report back on how I more or less solved this issue: I simply 
commented out the entry in /etc/bash.bashrc. Of course this is not the 
ideal approach, because the performance goes down as was shown in the 
link I mailed.

Kind regards,
Arjan Widlak.
