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).

# Red Bear OS Bare Configuration

#
|
|
# Target contract:
|
|
# - Boots kernel
|
|
# - Starts init daemons via a minimal base-initfs
|
|
# (logd, randd, zerod, ptyd, getty — see recipes/core/base-initfs)
|
|
# - Console getty → zsh login prompt (from minimal.toml's 30_console.service)
|
|
# - No networking, no driver-manager, no display, no audio, no extra daemons
|
|
# - Stripped to bare minimum
|
|
#
|
|
# To trigger the bare initfs (BINS=init logd ramfs randd zerod ptyd getty):
|
|
# REDBEAR_BARE_INITFS=1 make live CONFIG_NAME=redbear-bare
|
|
#
|
|
# Or via the build script with the env var set:
|
|
# REDBEAR_BARE_INITFS=1 ./local/scripts/build-redbear.sh redbear-bare
