I'd get one running and look at the open source. Book writing is big business, but code and playing tells you more. Also, there are many good pieces on open source products online. Get started first, and buy the book if you find you need help.

I also fancied a UFS variant where directories are trimmed, maybe even organized for hash or tree search. Another idea is a dir that can hold small inodes, files and directories within them, recursively, with dynamic expansion and initial/utility compression. Saves both inodes and pages. All invisible to old software, give or take a funny inode #.

Compression like zip is the thing that really fascinates me, as zip seeks to the compressed file you want, and as CPUs are faster than disks, the flow rates through zip may exceed most disk speeds. You could even chop a file into super-pages and compress each separately, for easier update and seek time within the file. Integration with the VM would allow all the decompressed file or superblock to be cached to VM. It could be rewritten back to disk as a redundant uncompressed copy in case of more query.

zip2st

ZIP2ST(1)							 Hatari utilities							 ZIP2ST(1)

NAME

       zip2st - a program for converting .zip archives to Atari .st disk images

SYNOPSIS

       zip2st srcname.zip [dstname.st]

DESCRIPTION

       zip2st can be used to convert a .zip file to a .st disk image.

       If  the	destination filename is not given, use the name of the .zip file, without the extension, and save it in the current working direc-
       tory.

       Any single directories (other than 'auto') at root of the zip archive are traversed down to avoid adding redundant intermediate directories
       from the zip file to the generated disk image.

       The .st disk image is a raw disk image, and can be written to a floppy using dd(1) or converted to .msa disk image with hmsa(1).

       The contents of the uncompressed zip file need to be smaller than 2.88MB (the largest floppy image size supported by Hatari).

SEE ALSO

       hmsa(1), atari-hd-image(1), hatari(1), unzip(1), mtools(1), dd(1).
