packages/bare-os-booter/lib/shell.js
$(...)/backticks are now enabled by default unless explicitly disabled via BARE_OS_SHELL_CMDSUBST=0|false|off.
Fixed sh -c exit/status propagation:
packages/bare-os-booter/lib/shell.js
Syncs BARE_OS_EXIT_STATUS after each executed statement so later commands in the same line (like echo $?) see the immediately previous status.
packages/bare-os-coreutils/src/sh.js
In -c mode, reads final BARE_OS_EXIT_STATUS back into ctx.exitCode for consistent result propagation.
Implemented trap behavior for requested scope (EXIT, INT, TERM):
packages/bare-os-booter/lib/shell.js
exit builtin now runs EXIT trap handler before requesting booter exit.
packages/bare-os-booter/index.js
Signal delivery for shell PID now triggers trap dispatch for INT/TERM.
Hardened ulimit -f invalid diagnostics:
packages/bare-os-coreutils/src/ulimit.js
Explicit invalid-value error for malformed -f setter input, with nonzero exit.
Supported-but-unimplemented setter values still return explicit unsupported-setter error.
Implement sh -c COMMAND [NAME [ARG...]] in /bin/sh, add shell function
declarations/invocation support, expand export semantics (NAME, NAME=value, -p),
and make until/loop-control behavior available by default. Add focused shell
tests and update sh man-page option docs.
sh, diff/patch, sort, printf, find, test, getfacl/setfacl/xattr), expanded
/proc and metrics (process table, syscalls, replication, net, security
posture, worker budget, swarm/replication hints), initd DAG supervision
metadata and richer restart journal telemetry, synthetic process groups via
IPC (assignProcessGroup/signalProcessGroup) mirrored into process_table,
optional kernel.ext.d incremental hot reload (BARE_OS_KERNEL_EXT_D_HOT_RELOAD)
with reload audit NDJSON, features proc for hyperblobs dedup and systemd
subset documentation, vault threat model doc plus posture fields for AEAD,
Pear enclave pointer, account rotation continuity, and Ed25519 consistency
across boot manifest / extensions / replication. Adds or extends tests and
keeps kernel/ and packages/bare-os-seeder/kernel/ in parity; guest init is
bundled from kernel/lib/init/init-main.js via bundle-kernel-init.
