Enable Singularity build on Liger
Right now it is not possible for users to build containers on Liger, as building requires root permissions.
It could be useful to exploit the --fakeroot
option that allows unprivileged users to build container safely. Right now the above option gives the following error:
FATAL: could not use fakeroot: no mapping entry found in /etc/subuid for drovelli
It would be good to configure it
