+# DEPRECATED / legacy single-version path. Superseded by the LONG-LIVED target:
+# serving/spdk/spdk-target.sh (persistent nvmf_tgt) + spdk-release.sh (online
+# add/remove of versions) + spdk-ctl.sh (host ops). This script configures ONE
+# version at start, so changing versions means restarting the container — which
+# drops EVERY running host's NVMe/TCP root connection (see docs/TODO.md #6). Kept
+# for reference / one-shot single-version use. The compose stack now runs
+# spdk-target.sh as the nvmeof entrypoint.

 # Configure SPDK nvmf_tgt to serve the diskless root filesystem as TWO READ-ONLY
 # NVMe/TCP namespaces — erofs DATA and the dm-verity HASH tree (design doc §5, §7).
