To: linux-8086
Interconnected patch to:
1. Incorporate a few files from bootblocks into the
source treeso linux-86 isn't necessary for compiling.
2. Move MAKEDEV and MAKESET out of rootfs_template to
save 12KB of space.
3. Fix I-don't-know-how-many-bugs in MAKEDEV.
4. Change /mnt/elks to /mnt/test.

You do realize that in your changes to the tar creation you omitted the
exclusion of "CVS" dirs?
Do we really want MAKEDEV and MAKESET out of rootfs_template?
Also, honestly it would be better to have a list of the bugs fixed
better than a "Fix I-don't-know-how-many-bugs in ..." line, because we
wouldn't know what you are doing.
