The whole magical-uid-0-user thing in this patch seem just wrong to
me.  

I'll merge it anyway, mainly because I want to merge _something_ (why oh
why do the git-tree guys leave everything to the last minute?) but it strikes
me that there's something fundamentally wrong whenever the kernel starts
"knowing" about the significance of UIDs in this fashion.

It worries me.
