Some follow ups
Is it a good thing running the Hugo blog as root? It is inside an unprivileged container - but still? Anyway it’s a simple mater to create a hugo user, add it to sudoers and then go back to the PVE and change the uid and gid of the NAS mount points so that they are now owned by user hugo. Then the blog, copied to the hugo home folder and chown’d appropriately should just work
