Bugzilla Bug 173826

I've been doing a bit of hacking on the netboot2 target. I just used the
following patch to build a minimal netboot image containing dropbear for x86.
Here's a summary of the changes I made:

* netboot2/packages/pkgname/files and netboot2/extra_files replaced with
  netboot2/packages/files (although, this could just become netboot2/files)
* netboot2/{rm,empty} options added
* netboot2/overlay added (overlays copied into /tmp/image for inclusion in
  initramfs
* builddate automatically generated for busybox config
* general cleanups

I like it, but I don't want it until 2.1 happens.

I think these should be fine since they won't break backwards compatibility.

Same as above.

> * builddate automatically generated for busybox config

I'm just curious why this is necessary.

> * general cleanups

What did you change?  I have no problems with general cleanups that don't break
backwards compatibility.

General cleanups:

* Moved various spec values to valid_values instead of requires_values
* Killed use of ${clst_root_path} in pre-kmerge.sh since it didn't make sense
and
  was "" anyway
* Killed custom set_dest_path() since settings["destpath"] isn't used in target
* Removed extra 'echo ""' at end of netboot2-copyfile.sh

There was a comment somewhere in the busybox stuff (don't recall where) that
busybox `date` needed a builddate in YYYYMMDD format.

This patch has some more enhancements (automatically creates netbootable image
on sparc64) as well as removing the changes that break backwards compatability
(netboot2/packages/foo/files+netboot2/extra_files -> netboot2/files).

It also relies on System.map-* being present in the kerncache tarball to
properly build a sparc64 netboot, but it will not break any other target if
using an older genkernel.

new new patch

This patch adds the netboot2/busybox_config option. If this option is
specified, the file is used to build busybox. If not, the default from
${clst_sharedir}/targets/netboot2/nb-busybox.cf is used. You will need to move
x86/nb-busybox.cf from genkernel into targets/netboot2/.

This adds a bit of code to netboot2-final.sh to run piggyback for sparc32 and
piggyback64 for sparc64 instead of piggyback64 unconditionally.

Alright... this patch is now applied to SVN...

This is fixed in 2.0.4 which was just released.
