no, when you change permissions on something they are generally
preserved by makedev.  but i rm -f'ed all my tty devices:

root@chrooted root# cd /dev/
root@chrooted dev# rm -f tty[0-9]*  # wheeee ;-)
root@chrooted dev# ls -l tty2
ls: tty2: No such file or directory
root@chrooted dev# ./MAKEDEV console
root@chrooted dev# ls -l tty2
crw-rw-rw-    1 root     tty        4,   2 Jul 10 05:13 tty2
root@chrooted dev# ls -l tty30
crw-rw-rw-    1 root     tty        4,  30 Jul 10 05:13 tty30
root@chrooted dev# ls -l tty12
crw-rw-rw-    1 root     tty        4,  12 Jul 10 05:13 tty12
root@chrooted dev# dpkg -s makedev | grep ^Ver
Version: 2.3.1-53
root@chrooted dev#
