Coding Assignment

First create three separate "drives" A, B, and C. Each is to have it's own

tree structure with directories and common files. Restrict the number of

files under each directory to no more than five. Each common file is to have

it's own i-node which need contain only filename, extension, and one line of

UNIQUE data (in lieu of a pointer to the data on "disk"). For simplicity,

do not make the depth of any directory tree exceed four levels.

On top of these file systems build a VFS that makes the three separate systems

appear as one big system. All user accesses should be via the VFS through

the v-nodes that you provide. The only functions that the VFS is to provide

is add a new file, delete a file, and "print"(show the one line of data) a

file. You must demonstrate all three operations and show the user's view of

the file structure, as well as, the actual file system structure before and

after each operation.

As before, all commands are to be entered via a GUI except that a data

file may be used to build the initial system (instead of entering the

pieces one file at a time).
