when do stdout, stdin, and stderr get created?

[Russell Coker <russell@xxxxxxxxxxxx>]

Currently on boot I see the following messages from devfsd:
error lstat(2)ing: "stdin"      No such file or directory
error lstat(2)ing: "stdout"     No such file or directory
error lstat(2)ing: "stderr"     No such file or directory

Where are these links created?  Why are they created in the early boot 
process?  Why not just have devfsd create them (or one of the boot scripts)?
