New Revision: 1877

Added a binary file that is supposed to be used when loading root.ext2 into
RAM (one needs to make a fake ZISO image containing only root.ext2).

TODO: implement the functionality mentioned above in the init.in script.

+The fakecd.iso.head file is stored in pregenerated binary form in order
+to avoid breakage that can be caused by new cdrtools. Append a single
+file compressed by mkzftree to it, and adjust DWORDs at offsets mentioned below
+in order to get a valid iso image containing that single file as /root.ext2.
+DWORDs to change:
+Offset 0xb8f8: compressed length, little-endian
+Offset 0xb8fc: compressed length, big-endian
+Offset 0xb973: uncompressed length, little-endian
+Offset 0xb977: uncompressed length, big-endian
+Uncompressed length can be found at offset 8 in the compressed file, in the
+little-endian form.
