V7 filesystem work

[Jonathan Naylor]

Hello All

A couple of weeks ago I hacked the program v7 from the bostic_tools to
work under all sorts of different Unix versions. It worked great and
allowed me to snoop around the V7 file system images from native Linux.
Anyone who wants a copy can send me an e-mail.

Anyway I had a few hours spare today, and decided to try adding the V7
filesystem to the Linux kernel. Results so far are encouraging:

I am using the loop block device to allow me to mount a file as a block
device, this saves me having to add a new partition to my disc. There
should be no reason why it won't work with a true disc partition. The V7
filesystem under Linux is read/write.

Anyone interested ?
