I don't think that will work because webcamd does the actually device
attach itself. Putting in the symlinks first _cant_ happen because there
is nothing to link to.

Again, same problem. webcamd does the work there to attach the devices -
but it uses hal to notify and obtain the numbering. I haven't found a
way to turn this off as yet. Originally I don't think it used hal at
all, somewhere along the line they decided to make inextricable.
I may be stuck with the cron job :/ I wonder if I can get it to just
happen at boot... my spidey senses are tingling. I'll have to remember
where I saw that.
