Track base 1769b083 (condition_path_exists for optional daemons, ahcid no-media,
netstack no-NIC idle, dhcpd fast-fail). Re-enable the serial debug console on
the bare target so it has a headless-visible login prompt (matching mini up to
login).

# 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
