[S] how do I create a link symbolic in Desktop through rules in udev ?

Question

Hi everyone!
My Rule:
[solano@localhost ~]$ cat /etc/udev/rules.d/01-montagem.rules
KERNEL=="sd[c-z]", NAME="%k", SYMLINK+="usb%m", GROUP="users", OPTIONS="last_rule"
ACTION=="add", KERNEL=="sd[c-z][0-9]", SYMLINK+="usb%n", GROUP="users", NAME="%k"
ACTION=="add", KERNEL=="sd[c-z][0-9]", RUN+="/bin/mkdir -p /media/usb%n"
ACTION=="add", KERNEL=="sd[c-z][0-9]", PROGRAM=="/lib/udev/vol_id -t %N", RESULT=="vfat", RUN+="/bin/mount -t vfat -o rw,noauto,flush,quiet,nodev,nosuid,noexec,noatime,dmask=000,fmask=111 /dev/%k /media/usb%n", OPTIONS="last_rule"
ACTION=="add", KERNEL=="sd[c-z][0-9]", RUN+="/bin/mount -t auto -o rw,noauto,sync,dirsync,noexec,nodev,noatime /dev/%k /media/usb%n", OPTIONS="last_rule"
ACTION=="remove", KERNEL=="sd[c-z][0-9]", RUN+="/bin/umount -l /media/usb%n"
ACTION=="remove", KERNEL=="sd[c-z][0-9]", RUN+="/bin/rmdir /media/usb%n", OPTIONS="last_rule"
I dont got configure my arch to create a icon in desktop when I plug a USB device, thus I try add a line in my udev.rules in /etc/udev/rules.d/01-montagem.rules to create a link in desktop when mounted device by add :
ACTION=="add", KERNEL=="sd[c-z][0-9]", RUN+="/bin/cp /media/usb%n /home/solano/Desktop/usb%n"
however it dont work, then I come here for help of you to try  'fix ' it.
Thanks and sorry by poor english.

Answer 1

Try these rules
ACTION=="add", KERNEL=="sd[c-z][0-9]", RUN+="/bin/ln -s /media/usb%k /home/solano/Desktop/usb%k"
ACTION=="remove", KERNEL=="sd[c-z][0-9]", RUN+="/bin/rm -f /home/solano/Desktop/usb%k"
The first rule should be placed before your mount rule and the second rule should be placed before your umount rule (it's important because mount rules are using OPTIONS="last_rule"). Also I'm using %k not %n because when you unplug your usb stick %n might return an empty string causing the second rule to not work. However if %n works for you (which means the link is created and deleted on usb stick removal) you can change %k to %n (the replacement must be done in all rules of course).
