I just completed installkernel and installworld. This is a FreeBSD 11.0-p7 Virtualbox guest. So I decided to look in the var/tmp and tmp to make sure that the tmproot directory was removed. It was, but I found these two files inside the tmp slice. I never seen this before in any previous version of FreeBSD. Would anyone know what these files are for? Is this something new for FreeBSD-11 or do they show up in previous versions that I miss such as 10.3? Are they harmful?
