- crates/core/README.md: agrupamiento lógico de los 31 crates absorbidos
de arje (ente-*) y del protocolo brahman (brahman-*) en 6 grupos —
Init/PID 1, contratos, discovery, IPC+CAS, cerebro, 14 shims compat
systemd. No se movieron crates físicamente (rompería paths
cross-workspace).
- seeds/arje-minimal.card.json: PID1 + /bin/sh, smoke test QEMU.
- seeds/arje-prod.card.json: PID1 + 14 shims compat + tmpfiles/binfmt
one-shots + echo + getty (16 children). Validados con
brahman_card::Card::validate.
- seeds/validate.sh: carga la seed vía ente-zero en dev mode.
- scripts/build-arje-initrd.sh: empaqueta CPIO+gzip newc layout
/init→/sbin/ente-zero, /usr/sbin/ente-*-compat, /ente/seed.card.json,
/bin/{sh,...} (busybox o glibc+ldd). Tested: produce 20 MB initrd OK.
- scripts/run-arje-qemu.sh: qemu-system-x86_64 con KVM auto-detect,
-kernel/-initrd/-append "rdinit=/init console=ttyS0,115200 panic=10".
- docs/arje-boot.md: doc end-to-end — layout initramfs, QEMU (con kernel
del host o externo), GRUB bare metal, Proxmox/libvirt args:, schema
de Card con todas las validaciones, debugging (sockets de
introspección, snapshot/restore, metrics), checklist pre-deploy.

# run-arje-qemu.sh — bootea el initrd de arje bajo qemu-system-x86_64.
|
|
#
|
|
# Uso:
|
|
# scripts/run-arje-qemu.sh [initrd] [kernel]
|
|
#
|
|
# Defaults:
|
|
# initrd out/arje.initrd.cpio.gz
|
|
# kernel $(uname -r) o /boot/vmlinuz-* (primer match)
|
|
#
|
|
# Env:
|
|
# QEMU binario de qemu (default: qemu-system-x86_64)
|
|
# KERNEL_CMD extra cmdline kernel (se concatena al fijo)
|
|
# MEM RAM en MB (default: 1024)
|
|
# SMP CPUs virtuales (default: 2)
|
|
# ACCEL kvm|tcg (default: kvm si /dev/kvm existe)
|
|
# HEADLESS 1 → sin display (consola en stdio)
|
|
#
|
|
# El initrd contiene su propio /init → ente-zero corre como PID 1 real.
