Sorry Tim. I meant putting the files which will go onto the images, not
the images themselves. Plus a tools/ script to build the images.

Perhaps we do the same as we have done with patches:
fs/root == original files as per s2 tape
fs/usr == original files as per s2 tape
fs/newfiles == new files to add to images
fs/buildroot == modified root (not in svn)
fs/buildusr == modified usr (not in svn)
tools/xxx == script to build root and usr

Current mkfs can write all the s2 files, including the large ones.

We can modify mkfs to restore uid, time and V1 permissions.

No, just document the method to build the kernels.

I think that's the way to go: a script to build a kernel + a set of
suitable tape/disk image files for it. Make it a top-level script
that calls next-level scripts, so that we can still run tools/assemv7
if we want to build a kernel and not build a filesystem.
