Updated kernel-runner delegate deny path to emit on stderr in packages/bare-os-booter/lib/kernel-runner.js. Added structured errno metadata (err.code) via vfsErr(...) and applied it to key VFS traversal/permission throws in packages/bare-os-booter/lib/vfs.js (ENOENT/EACCES paths). Critical command exit-code fixes: packages/bare-os-coreutils/src/ls.js Tracks access/stat failures and sets nonzero exit when any operand fails. packages/bare-os-coreutils/src/grep.js Recursive walker now reports traversal/stat errors back to main flow so fatal status becomes 2. packages/bare-os-coreutils/src/rm.js -f only suppresses not-found style errors; permission/deny failures stay nonzero. packages/bare-os-coreutils/src/chmod.js Treats falsy/no-op backend chmod result as failure (nonzero). packages/bare-os-coreutils/src/find.js Added root-path preflight so missing root now reports explicit error + nonzero. Minor quirks: packages/bare-os-coreutils/src/xargs.js -P0 now maps to bounded parallel cap (env/default cap), not forced serial. packages/bare-os-coreutils/src/ulimit.js -f with value now returns explicit unsupported-setter diagnostic + nonzero. -f alone reports unlimited. Regression tests: Added packages/bare-os-coreutils/test/error-propagation.test.mjs covering: grep missing file => exit 2 rm -f permission error => nonzero find missing root => nonzero + diagnostic ulimit -f 1M => explicit unsupported + nonzero xargs -P0 bounded behavior
bare-os-seeder
Pear / Bare application that owns the canonical system Hyperdrive: it walks a kernel tree on disk, writes /boot/init.js, /bin/*, /etc/* into the drive (no host temp dirs), builds a 512-byte MBR with the drive key, joins Hyperswarm on bare-os-v1, and serves MBR block reads + Protomux bare-os-v1 replication to peers.
When to use: run the seeder when you want to publish the canonical system image for booters to replicate (typical dev: one terminal with npm run os:seeder). Eligible already-booted peers can later mirror block 0, but the seeder remains the trust anchor for initial publication.

Run
From package directory (after npm ci at repo root):
node index.js
Or with Bare/Pear:
npm run pear:dev
From repo root (recommended — fixes workspace node_modules for Pear):
npm run os:seeder
Environment
BARE_OS_KERNEL_ROOT— Absolute path to kernel tree to stage (default: packagekernel/vendored copy, or repokernel/under Nodefile:URL)BARE_OS_HOST_DATA— Base directory for host state (default~/.bare-os)BARE_OS_SEED_STORE— Corestore directory (default~/.bare-os/corestore/seeder)BARE_OS_SEED_CAPABILITY_ATTESTATION_JSON— Optional JSON string for seed RPCbare_os.capability_attestation(operators verify on host; guest does not crypto-verify)
Pear vs Node
import.meta.urlisfile:— seeder may dynamically importbare-os-coreutils/build.mjsandbare-os-bare-libs/build.mjs, rebuilding/binandkernel/lib/barebefore staging.pear:bundle — coreutils and/lib/barebundles must be pre-built intokernel/; runnpm run build -w bare-os-coreutilsandnpm run build -w bare-os-bare-libsbeforepear run(rootnpm run os:seederdoes both).
