Edit: Although, in practice, you might be able to use the fact that readdir() seems to sort things itself by creation time, and create the scripts in the order you want them executed.

Good enough for me. I just wanted this:

N10usrmount: mounts my /usr partition (/dev/hda2)
N20myprog1: runs my program which resides on /usr

etc. Since my user programs all live on /usr I wanted to create one that executes first to mount it. The create time thing is fine for me.
