MKPROTO(8)                  System Manager's Manual                 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 sys-
       tem 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 direc-
       tions found in the prototype file proto.  The prototype  file  contains
       tokens separated by SPACE or NEWLINE characters.  The first tokens com-
       prise 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.
