[TUHS] ancient unix filesystems

[Sven Dehmlow]

Hi,
I'm currently working on an implementation of the Unix 6th Edition's 
filesystem for Linux. I think earlier Unix filesystems should be very 
similar to it. I would like to implement them, too, but I don't have 
exact descriptions of them (for the 6th Edition I've the Lions Book; 
there is not much about the actual filesystem architecture in it, but 
it should be enough - together with the code ;-).

Please send me descriptions, specifications and everything else 
you've about the early Unix filesystems. Also filesystem images are 
very welcome as I can use them to test my implementation.
My e-mail account can only handle attachments <3000KB. Please 
compress or split the files if they are bigger than 3000KB.

Thank you
Sven

Sven, you might want to look at this:

  From: Stuart Norris <norris at euler.mech.eng.usyd.edu.au>

 I have hacked together a version of a Unix 5th (and 6th) 
 Edition filesystem for Linux. It is read only, and was written for 
 Linux 2.0 on an x86 and so will require a little work to install on
 other systems and newer kernels, but it is fun to be able to mount 
 old disk images.

Cheers,

You might want to run V6 or V5 on a simulator. For one you can "see"
the filesystem and you can read the man pages, especially fs(5).
