# The DDNS simulator (RFC-2136-style /update) rewrites <domain>.zone on every
# registration, and Knot rewrites them on reload. If the zone files were
# bind-mounted directly from the repo (RW), those runtime writes would mutate
# version-controlled fixtures — and a DDNS update with no source IP used to
# stamp `@ IN A 0.0.0.0` straight into the repo's celilo.computer.zone (a
# prohibited cert-skip sentinel). Fix: fixtures are mounted READ-ONLY under
# /seed; copy them into the writable /config the sim + Knot actually use, so
# all runtime mutation stays container-local.
