This will print a lot of output, but it can mostly be ignored unless it fails.

Once that's done, CVMFS will be set up! It uses autofs for mounting, and should have installed + created an autofs mountpoint:
Check that the following file exists. Depending on your OS it might be /etc/auto.master as well.
# cat /etc/auto.master.d/cvmfs.autofs
# automatically generated by CernVM-FS
/cvmfs /etc/auto.cvmfs
If it doesn't, then run cvmfs_config setup. After which the following commands will work.
You can test the CVMFS client by exploring the cvmfs mounts:
# ls /cvmfs/data.galaxyproject.org/
byhand managed
# ls /cvmfs/data.galaxyproject.org/byhand

The folders will not be listed in /cvmfs by default, you can see these by listing the configured repositories:
# cvmfs_config showconfig | grep CVMFS_REPOSITORY_NAME
CVMFS_REPOSITORY_NAME=test.galaxyproject.org
CVMFS_REPOSITORY_NAME=main.galaxyproject.org
CVMFS_REPOSITORY_NAME=data.galaxyproject.org
CVMFS_REPOSITORY_NAME=sandbox.galaxyproject.org
CVMFS_REPOSITORY_NAME=singularity.galaxyproject.org
# ls /cvmfs/main.galaxyproject.org
bin config deps fontconfig galaxy migrated_tools python shed_tools tags.txt tmp tool_data var venv
This will also tell you that we distribute Singularity containers by default. Have a look at ls -l /cvmfs/singularity.galaxyproject.org/ to see more.
