The point is: we're not.

Agreed—and you wrote "despite my emasculation of udev, disabling sdd,
according to the syslog, usbmount is still auto mounting these cards".

Hence my abrupt comment "Oh my, what did you expect?" and the rather
obvious point that usbmount advertises itself as an automounter.

Then you denied that usbmount was installed: "No such critter on this
wheezy box." Hence my "This is getting silly."

Then, having admitted that you do have it installed, you now blamed it
or udev for doing something on your Desktop, which they probably know
nothing about; udev is operating only just above the kernel.

So at this point I pointed out that it might not be wise to fiddle
about with udev's files too much because rather a lot of subsystems
may rely on its working properly.

and that is the problem that Thomas has been helping you with, in a
far better way than I ever could.

If I have an attitude, it's this. The list's readers will be familiar
with the fact that you often seem to run into problems where others
find no difficulty. Often, you post some of the actions to take in
trying to fix such problems. Ofttimes again, these steps appear to be
fighting the system rather than working with it.

What I saw here was you cudgelling udev when something else was to blame.
The persistent-storage rules are meant to allow the system to recognise
what device changes are taking place so that it can assign the right
names both for you and for subsystems further up the chain.

My goal was to help steer you in the direction of what might be causing
your specific automounting problem so that you might reach a better
solution without breaking other things.

In the meantime, I can't just post an easy fix because, again as we
all know, you run a mixture of systems of different ages, much of it
oldoldstable, on different architectures, and with kernels that are
not even Debian's. Add to all that the fact that I don't have any
experience of configuring DEs because I've only briefly seen them
when I have booted from a live stick, so I can only try and ask
Socratic questions that might suggest where you could look.

And, because this is just a list, you can always ignore any
suggestions I make.

Cheers,
David.
