No, they don't require /dev/console just to operate, but if you want 
debug printout they do :)

Init could easily reopen its controlling terminal to the created 
/dev/console and continue ...

The reason I was looking at getting init to create /dev/console was so 
that I could debug my init scripts that are not working when 
/dev/console does not exist ...
