- == Beyond Buildroot
- === Boot the generated images
- ==== NFS boot
- To achieve NFS-boot, enable _tar root filesystem_ in the _Filesystem
- images_ menu.
- After a complete build, just run the following commands to setup the
- NFS-root directory:
- -------------------
- sudo tar -xavf /path/to/output_dir/rootfs.tar -C /path/to/nfs_root_dir
- -------------------
- Remember to add this path to +/etc/exports+.
- Then, you can execute a NFS-boot from your target.
- ==== Live CD
- To build a live CD image, enable the _iso image_ option in the
- _Filesystem images_ menu. Note that this option is only available on
- the x86 and x86-64 architectures, and if you are building your kernel
- with Buildroot.
- You can build a live CD image with either IsoLinux, Grub or Grub 2 as
- a bootloader, but only Isolinux supports making this image usable both
- as a live CD and live USB (through the _Build hybrid image_ option).
- You can test your live CD image using QEMU:
- -------------------
- qemu-system-i386 -cdrom output/images/rootfs.iso9660
- -------------------
- Or use it as a hard-drive image if it is a hybrid ISO:
- -------------------
- qemu-system-i386 -hda output/images/rootfs.iso9660
- -------------------
- It can be easily flashed to a USB drive with +dd+:
- -------------------
- dd if=output/images/rootfs.iso9660 of=/dev/sdb
- -------------------
- === Chroot
- If you want to chroot in a generated image, then there are few thing
- you should be aware of:
- * you should setup the new root from the _tar root filesystem_ image;
- * either the selected target architecture is compatible with your host
- machine, or you should use some +qemu-*+ binary and correctly set it
- within the +binfmt+ properties to be able to run the binaries built
- for the target on your host machine;
- * Buildroot does not currently provide +host-qemu+ and +binfmt+
- correctly built and set for that kind of use.
