MKPROTO(8)

NAME
mkproto - construct a prototype file system

SYNOPSIS
/usr/etc/mkproto special proto

DESCRIPTION
mkproto is used to bootstrap a new file system. First a new file system is created using newfs(8). mkproto is then used to copy files from the old file system into the new file system according to the directions found in the prototype file proto. The prototype file contains tokens separated by SPACE or NEWLINE characters. The first tokens comprise the specification for the root directory. File specifications consist of tokens giving the mode, the user ID, the group ID, and the initial contents of the file. The syntax of the contents field depends on the mode.

The mode token for a file is a 6 character string. The first character specifies the type of the file. (The characters -bcd specify regular, block special, character special and directory files respectively.) The second character of the type is either u or `-' to specify set-user-id mode or not. The third is g or `-' for the set-group-id mode. The rest of the mode is a three digit octal number giving the owner, group, and other read, write, execute permissions, see chmod(1V).

Two decimal number tokens come after the mode; they specify the user and group ID's of the owner of the file.

If the file is a regular file, the next token is a pathname whence the contents and size are copied.

If the file is a block or character special file, two decimal number tokens follow which give the major and minor device numbers.

If the file is a directory, mkproto makes the entries `.' and `..' and then reads a list of names and (recursively) file specifications for the entries in the directory. The scan is terminated with the token $.

A sample prototype specification follows:

    d--777 3 1
    usr	d--777 3 1
        sh	---755 3 1 /usr/bin/sh
        ken	d--755 6 1
            $
        b0	b--644 3 1 0 0
        c0	c--644 3 1 0 0
        $
    $

BUGS
There should be some way to specify links.

There should be some way to specify bad blocks.

mkproto can only be run on virgin file systems. It should be possible to copy files into existent file systems.
