[eudev] fd0 and sr0 in /proc/partitions ?

[David F.]

Hi,

I was trying to find what populates /proc/partitions, and from what I
found, it said it was the kernel, but I don't think so, because using
the same kernel, one using older udev has no fd0 in /proc/partitions,
the newer one has fd0 in there; both have sr0 in there for some
reason.  So is it udev that is doing that?  If so, why or how does it
put that in there?

I also don't understand what the rules are all about, you set
environment variables, like this udisks2 rule with setting
ID_DRIVE_FLOPPY to 1, but that's the end of it as I see, so it's like
it does nothing?   I don't get it?

So is there a way to setup a rule to prevent fd0 from going to
/proc/partitions or something like that?

TIA!!
