    Description

      As reported for sft-nightlies.cern.ch, there has been a problem at the end of a publication when it comes to remounting the /cvmfs/sft-nightlies.cern.ch overlayfs stack. Concretely, the read-only mount point did not come back:

      [cvsft-nightlies@lxcvmfs146 ~]$ systemctl status "var-spool-cvmfs-sft\x2dnightlies.cern.ch<http://x2dnightlies.cern.ch>-rdonly.mount"
      ‚óŹ var-spool-cvmfs-sft\x2dnightlies.cern.ch<http://x2dnightlies.cern.ch>-rdonly.mount - /var/spool/cvmfs/sft-nightlies.cern.ch/rdonly<http://sft-nightlies.cern.ch/rdonly>
         Loaded: loaded (/etc/fstab; bad; vendor preset: disabled)

      The system log shows

      -- Unit var-spool-cvmfs-sft\x2dnightlies.cern.ch-rdonly.mount has begun starting up.

      This could be a race condition in the presence of frequent publications.
