Port the brush shell (reubeno/brush) to Redox and adopt the recipe as a
Red Bear local recipe under local/recipes/shells/brush, with the standard
recipes/shells/brush -> ../../local/recipes/shells/brush overlay symlink so
it takes priority over any upstream WIP copy (per local/AGENTS.md "Local
recipe priority vs upstream WIP"). Removes the old recipes/wip/shells/brush.
The dependency tree did not build for Redox: nix 0.31 only partially
cfg-enables Redox and the libc crate's Redox module omits POSIX symbols that
relibc provides. Fixes are reviewable unified diffs under
local/recipes/shells/brush/patches/:
nix-0.31-redox.patch cfg-enable resource/Id/waitid/from_siginfo, rlimit
import + repr(i32), SaFlags width casts, pty.
libc-0.2-redox.patch add idtype_t, P_*/CLD_*, rusage, getrusage/waitid/
forkpty externs, siginfo child accessors.
brush-umask-redox.patch mode_t is signed on Redox; cast, not u32::from.
The recipe runs `cargo fetch` to materialise registry sources before
patching (they are only unpacked during the build), resolves the right
crate version from Cargo.lock (brush pulls both nix 0.26 and 0.31), and
applies each patch idempotently, failing loudly on version drift. The
binary target is named `brush` (not `brush-shell`), so install it
explicitly. Verified: cooks from a pristine cargo cache using only the
patch files. brush is shipped in redbear-mini as a package for in-image
validation; the login shell stays zsh until brush is runtime-proven.
Base submodule 1f826240: 00_pcid-spawner (/usr) and 10_smolnetd base-default
init units switched to oneshot_async so init never blocks the boot-to-login
path on PCI driver enumeration or a network adapter binding. Adds the
2026-07-16 CHANGELOG entry (mini login restored, kernel MSR #GP guard,
build-system staleness/lock/override fixes).
Mini now boots (q35/KVM) all the way to the getty "Red Bear login:" prompt
on VT2 with zero kernel panics. Root-cause fixes across submodules + config:
- config: 00_base.service zsh->mkdir (a full shell startup hangs an init
oneshot; the earlier 'echo/mkdir also hang' result was a silent config
override running zsh). 00_ptyd.service notify->{scheme=pty} (ptyd signals
readiness via its scheme fd; notify made init block on a byte forever).
- kernel: wrmsr_safe/rdmsr_safe #GP recovery so /scheme/sys/msr can't panic
the kernel (cpufreqd's P-state MSR write #GP'd on KVM, halting the boot
before login). base: ptyd scheme type + hwd ACPI enum -> debug (noise).
installer: warn on config [[files]] override. relibc/bootloader: prior
getrlimit + warning-demotion pointers.
- build-redbear.sh: fix host-fstools staleness (installer/redoxfs never
rebuilt on source change), prefix rebuild-every-build (touch libc.a), add
concurrent-build flock.
Submodule pointers: base 8aa8616d, installer 460d9530, kernel 155d01b1,
relibc a7663b3a, bootloader 6e119641.
The thr_fd.take() and mem::forget(proc_fd) workarounds were
intended to keep the parent's proc scheme handles alive after
posix_spawn returns, so the child's ld_so could use them via
AT_REDOX_*_FD auxv entries. The boot diagnostic shows the actual
relibc binary does NOT take the 'fork' / 'thread-0' kdup path
(those calls never appear in the kdup trace), so the workarounds
targeted a code path that was not running. The real fix is
kernel-side: each Context must hold a self-reference to its own
proc handle so the handle cannot be dropped while the context
is alive.
Multiple fixes to make redbear-bare actually build and progress
through boot:
config/redbear-bare.toml:
- filesystem_size: 96 -> 192 MiB. The bare image packages ~153 MiB
of installed content (zsh, base, base-initfs, kernel, relibc,
userutils, libgcc, libstdcxx, plus coreutils/extrautils/etc.),
so 96 MiB triggers installer ENOSPC during commit.
- Override 31_debug_console.service with postinstall=true so the
override wins over minimal.toml's version that uses
/scheme/debug/no-preserve (which busy-loops when the debug
scheme returns ENODEV in the bare initfs).
recipes/core/base-initfs/recipe.toml:
- bare_initfs() now only references BINS in the base workspace
(init, logd, ramfs, randd, zerod, ptyd). getty is removed from
BINS because it lives in userutils, not base.
- Copy getty from the sysroot into the initfs after the cargo
build (analogous to the existing redoxfs/ion/driver-manager
sysroot copies).
- Filter the init.d copy under REDBEAR_BARE_INITFS to keep only
services for binaries we actually built (logd, randd, zerod,
runtime.target, ramfs@.service, 90_initfs.target, 50_rootfs).
The mainline 23 services reference fbcond/vesad/acpid/pcid/
fbbootlogd/hwd/inputd which aren't in the bare BINS, so
init would try to start them and busy-loop.
- Synthesize minimal 00_ptyd.service and 30_getty.service units
in the initfs since they're built/copied but not in the
mainline init.initfs.d.
- Override 00_runtime.target to add ptyd and getty as weak
requires (the mainline target references nulld/rtcd which we
filtered out).
Kernel is built with target-feature=+soft-float (no SSE), but the
upstream ProcUptime code used f64 in format!() which requires SSE
register return. This caused a build error:
error: src/scheme/proc.rs:2047:32: ... SSE register return with
SSE disabled
Replace the f64 arithmetic with integer math (seconds.milliseconds)
to make the kernel buildable on the redoxer cross-toolchain.
The redbear-bare target (added in 48a6f4c20b) was not registered in
the build dispatchers. Running build-redbear.sh redbear-bare
silently exited with 'ERROR: Unknown config redbear-bare'.
Fix:
- build-redbear.sh: extend the case statement + usage block + error
message to include redbear-bare
- integrate-redbear.sh: add config/redbear-bare.toml to the configs
array so source-tree integration picks up the bare target too
- build-all-isos.sh: include redbear-bare in the targets list
This closes the gap where the bare target existed as a config file
and as a recipe branch (REDBEAR_BARE_INITFS) but was invisible to
the build dispatch layer.

Round-25 fix landed the bare initfs conditional in
recipes/core/base-initfs/recipe.toml but the cookbook does NOT parse
[build.env] sections in TOML configs. The REDBEAR_BARE_INITFS=1
env var I put in redbear-bare.toml was silently ignored.
Fix: propagate REDBEAR_BARE_INITFS through build-redbear.sh's make live
invocation. When CONFIG=redbear-bare and the operator has not already
exported REDBEAR_BARE_INITFS, auto-set it to 1 so the bare initfs
branch is triggered. Also propagates any pre-existing REDBEAR_BARE_INITFS
through the make call (override-only).
Also rewrote the [build.env] section in redbear-bare.toml to a
comment-only section explaining the dispatch mechanism, since the
cookbook parser ignores it.

Address 4 gaps in the new redbear-bare target per review:
Gap 1: add REDBEAR_BARE_INITFS env var to base-initfs recipe. When
set, BINS=init logd ramfs randd zerod ptyd getty instead of 22+
daemons/drivers. The bare target can now opt into the truly-minimal
initfs via the env var.
Gap 2: add ptyd and getty to the cp case-list so they go to /initfs/bin
not /initfs/lib/drivers. Without this, the getty 2 service cannot
start because ptyd (which it requires) isn't in the initfs.
Gap 3: add /etc/issue (pre-login banner) and /etc/motd (post-login
message) to the bare config. Standard Unix login surface polish.
Gap 4: trim packages in the bare config. Override ca-certificates,
pkgutils, kibi (from minimal.toml) to empty. Bare only needs:
zsh, coreutils, base, base-initfs, kernel, relibc, userutils,
libgcc, libstdcxx.
Build invocation:
REDBEAR_BARE_INITFS=1 make live CONFIG_NAME=redbear-bare

Strips to bare minimum: kernel boots, base-initfs 90_initfs.target
brings up init daemons (logd, randd, zerod, ptyd, inputd), console
getty 2 hands off to zsh as default shell. No networking, no
display/audio, no driver-manager, no extra services.
filesystem_size=96 MiB. Includes only minimal.toml. Overrides
base.toml's /etc/net/* and /etc/pkg.d/50_redox (empty) and
/etc/login_schemes.toml (display/audio removed).

The script uses '${BRANCH_VERSION:-0.0.0}' as the +rb suffix when
bumping a fork to a new upstream version. BRANCH_VERSION was never
set, so any fork bump would have produced 'X.Y.Z+rb0.0.0' instead
of the correct 'X.Y.Z+rb0.3.2' (or whichever branch is current).
Derive BRANCH_VERSION from 'git branch --show-current' using the same
pattern as local/scripts/build-redbear.sh:158-165. Falls back to
'0.0.0' if the branch name doesn't match semver (e.g., on 'master').
