mkproto - Constructs a prototype file system
mkproto special proto
The mkproto command is used to bootstrap a new file system. First a new
file system is created using newfs. 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 newlines. The first tokens comprise the specifica-
tion 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 a u or a - (dash) to specify setuid
mode or not. The third character is either a g or a - (dash) for the setgid
mode. The rest of the mode is a 3-digit octal number, giving the owner,
group, and other read, write, execute permissions. (See the chmod(1) com-
mand for more information.)
Two decimal number tokens come after the mode; they specify the user and
group IDs of the owner of the file:
+ If the file is a regular file, the next token is a pathname from which
the contents and size are copied.
+ If the file is a block-special or a character-special file, two
decimal number tokens follow, giving the major and minor device
+ If the file is a directory, mkproto makes the entries . (dot) and ..
(dot dot) and then reads a list of names and (recursively) file
specifications for the entries in the directory. The scan is ter-
minated with the token $.
