s6-overlay v3.2.0 adds tolerance for unprivileged containers with world-writable /run, enabling containers to run as non-root in Kubernetes/OpenShift environments. This adds support for the S6_YES_I_WANT_A_WORLD_WRITABLE_RUN_BECAUSE_KUBERNETES environment variable which allows s6-overlay to boot when /run is owned by uid 0 but the container runs as a different user. Fixes running Home Assistant on OpenShift where containers are assigned random UIDs and cannot chown /run. Ref: just-containers/s6-overlay#427

Summary
Update s6-overlay from 3.1.6.2 to 3.2.1.0 to enable running Home Assistant containers as non-root in Kubernetes/OpenShift environments.
Problem
Home Assistant containers fail to start on OpenShift (and other Kubernetes distributions that enforce non-root) with:
OpenShift runs containers with random UIDs (e.g.,
uid=1000780000) that cannot chown directories.Solution
s6-overlay v3.2.0 added:
This release introduces
S6_YES_I_WANT_A_WORLD_WRITABLE_RUN_BECAUSE_KUBERNETESenvironment variable support that allows s6-overlay to boot with world-writable/runowned by uid 0.References
