Make a link to one ore more other /dev entries (I suppose that is already
the case; maybe /dev/console is linked to /dev/crt or somethink similar;
check either the inodes or major/minor numbers to see it it is already
present).

For example, execute 'ln /dev/console /dev/systty'. If it then happens that
someone deletes /dev/console, you still have /dev/systty and can relink it
to /dev/console.
