Two days ago, during a docker build, Dwellers unexpectedly rebooted.
This behavior hasn't been reproduced: consequent builds of the same images. Log doesn't contain any relevant error information.
A docker build operation involves network and partitions manipulations.
We noticed SELinux don't allow /etc/hosts to be read by former containers after a reboot, so Dwellers will definitively run in SELinux Permissive mode: any SELinux policy infraction will be logged, but allowed.
