* use "ln -fs foo bar" instead of "rm -f bar; ln -s foo bar" * remove unnecessary chown root or chgrp wheel directives; older code here didn't bother doing this, so why be inconsistent * when making directories, don't use -p and don't redirect stdout to /dev/null * clean up whitespace * wrap the main parser code in a function makedev(), and call makedev instead of "sh $0". (this is a bit faster) * don't barf when we have fdesc mounted; just skip the devices fdesc provides (these files should really be automagically generated...)
