This new Native version for Linux should work even if CVMFS has not been installed.

It won't work on SL6 as we need a later kernel for rootless containers.

Here is a CentOS7 Task.
https://lhcathomedev.cern.ch/lhcathome-dev/results.php?hostid=3830
Had first forgotten the namespaces command:
echo 640 > /proc/sys/user/max_user/namespaces

After setting this command got this Error:

Installation of cvmfs come from Docker and why is it cvmfs-2.6.0 ?
Will test it again with a reboot after deinstallation of cvmfs.

No you didn't miss anything. The CVMFS code we are using does not work on all Linux flavours. We need to rebuild to make it supports more platforms.

Have tested -dev native and Production -native in ONE Boinc under Linux SL76.

In -dev there is always creating a new slot-number when a new task is running.
The old slot is empty after task is finished, but a new slot-number is taken.

When slot number 100 is reached than Boinc send a message and no new task is running.

Seems to be quite a few of these 195 errors where the Tasks fail around the same point (90mins or so) for all 3 users.
