Purpose: illustrate how to use Yocto to build a minimalist rootfs.
- minimal Root FS (busybox only, no network)
- one init script
- one user (root, empty password)
Manifest:
base-files qemux86_64 3.0.14b-r0
busybox core2-64 1.32.0-r0_minimal
initscripts core2-64 1.1-r0
libc6 core2-64 2.32-r0
- Yocto branch gatesgarth (yocto-3.2)
- bzImage: 8.8 MBytes
- Root FS: 4.4 MBytes
