mkproto - construct a prototype file system
/usr/sbin/mkproto special proto
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 spaces or new lines. The first tokens comprise the specifi-
cation 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 spec-
ify 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
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.
Mkproto can only copy files up to a single level indirect less 4kb. This works out to
