# zddc-cgroup-init prepares cgroup v2 subtree_control then
# exec's zddc-server. Required because cgroup v2 forbids
# processes in a cgroup that has child cgroups; the per-
# conversion wrapper (zddc-sandbox-exec) creates child
# cgroups for resource caps, so the init script has to
# move zddc-server itself out of the root cgroup first.
# See zddc/runtime/zddc-cgroup-init in the source repo.

# The conversion sandbox (bwrap, invoked per-call by
# /usr/local/bin/{pandoc,chromium-browser}) needs to create
# user + mount namespaces inside the container. Pod Security
# Standards default policies forbid this; the chart sets the
# minimum securityContext that lets bwrap function. If your
# cluster's admission controller rejects these settings, you
# have two choices: ask the platform team to allow this pod,
# or accept that /.convert serves 503 (the rest of zddc-
# server still works fine without conversion).

# specifying seccompProfile + appArmorProfile fields;
# if your cluster is older, you'll need annotations:
