single partition & no initramfs linux boot gets kernel panic

  • compiled a kernel using gentoo specifications for Thinkpad T430

  • mounted empty ext4 hard drive and created boot/ directory on it, moved bzImage and System.map inside

  • Installed extlinux to it with "extlinux --install [mounted directory]/boot"

  • placed syslinux.cfg inside with the following config:

    DEFAULT linux
  SAY Now booting the kernel from EXTLINUX...
LABEL linux
  KERNEL /boot/bzImage
  APPEND root=/dev/sdb rw init=/bin/bash

  • Created bin/ folder in mounted hard drive, placed bash binary inside

At this point i'm able to boot the kernel to the point where it has to run init, however it panics:

---[ Kernel Panic - not syncing: Requested init /bin/bash failed (error -2). ]---
