How to hide on desktop unmounted partitions

Bonjour,

I have on my disks some partitions which are not mounted at boot time
and they appear as icons on the desktop of every user... I want to
hide them.

Before systemd, I added some rules in udev directories
(/etc/udev/rules.d) to hide these partions:

KERNEL=="sda1", ENV{UDISKS_PRESENTATION_HIDE}="1"
KERNEL=="sda2", ENV{UDISKS_PRESENTATION_HIDE}="1"
ACTION=="add", KERNEL=="0000:00:02.0", SUBSYSTEM=="pci", RUN+="/bin/sh
- -c 'echo 1 > /sys/bus/pci/devices/0000:00:02.0/remove'"

And partitions sda1 and sda2 do not appear on desktop...

Is it possible to do the same with systemd-udevd? What is the right
syntax?

One more question: these partitions are members of raid arrays and lvm
groups, is it possible to use md2 or /dev/mapper/foo instead of sda1,
sda2....

Thank you for helping (I am very new to systemd...)

So! I answer to myself... This can be usefull for people who have
several systems installed and who use xfce (I don't know if the same
problem occurs for kde or gnome): icons of partitions of other system
show on the desktop.

Create a file (98-local.rules for instance) in /etc/udev/rules.d with:

ENV{ID_FS_UUID}=="17e0b155-4d77-4769-b568-723329c5f656", \
ENV{UDISKS_IGNORE}="1"

for each partition you want to hide.

You can find the right syntax, ENV{ID_FS_UUID} for instance, with the
command:

udevadm info /dev/md2

After reboot, icons do not show on the desktop.
