I just had it brought to my attention that the unix kernel is mode 777
in Unix v5 and v6:
ls -l /unix
-rwxrwx 1 root 27066 Mar 23 1975 /unix
There's no reason for it to be mode 777 is there? It seems rather dangerous.
In Unix v7 it defaults to mode 775 and in 32v it is 755. I figure it
setting it to mode 755 will work and so far it seems fine in v5.
