Pull request in Singularity (to enthusiastically update!):

Test releases with "underlay" feature to test:

Underlay is enabled by default in /etc/singularity/singularity.conf if
overlay does not work.  On EL7 you can disable overlay by setting the
environment variable SINGULARITY_DISABLE_OVERLAYFS=1, by setting enable
overlay = no in singularity.conf, or by using the exec "-u" option to
run unprivileged (assuming you have enabled unprivileged user namespaces).
