I have setup a Boinc VM running as a container under LXC on Proxmox.
All projects seem to work fine except for CERN and the CVMFS based apps.

I've changed the container to run with an "unconfined" profile still all tasks requiring CVMFS fail at even detecting cvmfs program

Example log:

A "cvmfs_config probe" returns OK for all targets when ran manually.

Any help appreciated.
