# NOTE: Package management requires extensive system access. The following
# restrictions have been removed because they block core functionality:
# - ProtectSystem=strict: Blocks writes to /usr, /etc, /lib where packages install
# - NoNewPrivileges: Blocks sudo/setuid which apt needs for _apt sandbox
# - RestrictSUIDSGID: Blocks setuid/setgid which apt needs for _apt sandbox
# - CapabilityBoundingSet: Drops capabilities that apt needs (SETUID, SETGID, CHOWN, etc.)
# - AmbientCapabilities: Same issue as CapabilityBoundingSet
# Network security is provided by mTLS + IP whitelist. The service runs as root
# and MUST be able to install/remove/update packages system-wide.
