galaxyproject.cvmfsexec

An Ansible role for building the cvmfsexec and cvmfsexec commands from the cvmfsexec package. The cvmfsexec utilities assist in performing unprivileged user-namespace CVMFS mounts, optionally in an Apptainer (Singularity) container, even if the host does not have CVMFS or a new enough version of FUSE 3 installed. See the cvmfsexec documentation for details.
