?? What's uncommon about that ? I don't care what anyone does with
his/her own usb disks on his/her own machine. It's not my business.
I *do* care if users connect an usb disk to my machine.

What makes you think that the configuration I use is 'too coarse
grained' ??

That's what any security system does, so rather irrelevant.

And in fact it has the opposite effect: just installing some
packages that use PK can suddenly allow things that were not
allowed before. The only way to avoid that is to ship all
PK enabled packages with 'unix permissions only', and that
is certainly not what I see happen.
