Since autofs is often used in conjunction with ypbind, it's a good idea to start ypbind before autofs. Therefore, the default /etc/init.d/autofs should be changed from depend() { need net } to depend() { need net use ypbind } One could argue that the same applies for LDAP, but I haven't tested that.
