mkproto - construct a prototype file system
/etc/mkproto special proto
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 spaces or new lines. 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 con-
tents of the file. The syntax of the contents field depends on the
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(1).
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 /bin/sh
ken d--755 6 1
b0 b--644 3 1 0 0
c0 c--644 3 1 0 0
fs(5), dir(5), fsck(8), newfs(8)
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.
