to a particular file.

mkbootfs uses the compiled in fs_config() function to set the mode
(but not the uid or gid) of the files in the filesystem it is
building. Give it an optional "-f filename" flag to allow loading the
list of file permissions from a file, so we can continue to accurately
recreate old filesystems even when the current fs_config() has changed.
