# Confine all writes to the state dir. See debian/bewitch.bewitchd.service for the
# full rationale and the directives deliberately left unset (PrivateDevices,
# PrivatePID, SystemCallFilter, MemoryDenyWriteExecute) that would break SMART,
# eBPF, or the CGO DuckDB engine. This minimal unit omits the elevated
# capabilities; add the AmbientCapabilities / SupplementaryGroups from the Debian
# unit if you need SMART / GPU / per-process disk+network I/O.
