Device driver question (attach entry point)

[John Snyders]

I am writing a pseudo device driver for unix (actually ultrix, but the answer
should be the same as for BSD unix?).

My question is how do you get an attach entry point to be called during system
boot? Can pseudo devices have an init routine?

Please e-mail answers, thanks. Sorry if this got posted twice.
