Stop long-running daemon operations from running under context.Background by\nthreading a request-scoped context from handleConn into dispatch. The daemon\nnow cancels in-flight handlers when the client socket goes away, and the RPC\nclient closes its Unix connection when the caller context is canceled so that\ninterrupts actually reach the daemon boundary.\n\nAdd regression coverage for both sides of the path: canceled dispatch calls,\nclient disconnects during handleConn, watcher EOF cancellation, and context\ncancellation without an RPC deadline.\n\nValidated with GOCACHE=/tmp/banger-gocache go test ./... and\nGOCACHE=/tmp/banger-gocache make build.
Upgrades from the pre-bundle layout can leave the unmanaged default image pointing at repo-root artifacts that no longer exist, causing vm start preflight to fail forever. Treat the default image as reconcilable state instead of bailing out when a record exists.
Compute the desired default image from current runtime/config defaults, update an existing unmanaged default in place when its paths diverge, keep managed defaults untouched, and preserve the original ID so existing VMs keep referencing it. Added regression tests covering creation, no-op, reconciliation, managed-image skip, and missing-artifact behavior.
Stop assuming one workstation layout for runtime artifacts, mapdns, and host tooling. The daemon and shell helpers now use portable mapdns configuration, and runtime bundles can carry bundle.json metadata for their default kernel, initrd, modules, rootfs, and helper paths.
Load bundle metadata through config with a legacy layout fallback, thread mapdns_bin/mapdns_data_file through the Go and shell paths, and add command-scoped preflight checks for VM start, NAT, image build, work-disk resize, and SSH so missing tools or artifacts fail with actionable errors.
Update the runtime-bundle manifest, docs, and tests to match the new model. Verified with go test ./..., make build, and bash -n customize.sh interactive.sh dns.sh make-rootfs.sh verify.sh.
Fix the misleading make install path where banger and bangerd still depended on a repo checkout for Firecracker, guest artifacts, image builds, and the SSH key.
Replace repo-root inference with an explicit runtime bundle model: resolve a runtime_dir from env/config/install layout, derive concrete artifact paths from it, and update the daemon, CLI, and image-build flow to use those paths. Keep repo_root only as an explicit compatibility alias instead of auto-detecting it.
Teach customize.sh to run from a read-only bundled runtime tree while writing transient state under XDG/BANGER_STATE_DIR, and make make install copy the runtime assets into PREFIX/lib/banger so installed binaries stay usable outside the repo.
Validate with go test ./..., make build, bash -n customize.sh, and make install DESTDIR=/tmp/banger-install PREFIX=/usr. An out-of-repo installed-binary smoke test was attempted, but this sandbox blocked bangerd from binding its Unix socket (setsockopt: operation not permitted).
