I've got init past the link, but it then dies on the open("sh") immediately
...
after that. Yes, dd has to be i-num 4. I've modified mkfs7 and the proto
file to allow this to occur. I've also make link counts negative.

I've added code to mkfs7 to build a free block list, to write it out to
...
the disk image, and to add a pointer in block zero to the beginning of
the list.

So, SimH stores things big-endian. Fixed mkfs7.

More mkfs changes as Phil tries to get the kernel up to reading init.

Get mkfs7 to write 8000 empty blocks to fill the bottom half before the
...
real filesystem in the top half.

Changed the filesystem proto file and enhanced the mkfs7 tool based on
...
Phi's analysis of the filesystem.

Oops, I forgot to actually write the file contents into the filesystem image.

I've written more of mkfs7 but not tested it yet.

I've made a start on a mkfs tool for PDP-7 Unix. So far I have the routines
...
to build the filesystem, but they are not tested. I need to add code to
parse the "proto" file, whose syntax is based on the 6th Edition proto file.
I also need to dump out the filesystem image.
