Title:
  udev name/symlink rules give permission denied error

Status in udev package in Ubuntu:
  Invalid

Bug description:
  Binary package hint: udev

  I was just trying to create a rule to create a /dev/lirc symlink from the appropriate
  /dev/input/event* but kept running into permissioning issues.

  The following udev rules (both give the same result) when placed in
  /etc/udev/rules.d/10-local.rules:

  KERNEL=="event*",ATTRS{vendor}=="0x14f1",SYMLINK+="lirc"
  #KERNEL=="event*",ATTRS{vendor}=="0x14f1",NAME="lirc"

  ...should produce a symbolic link at /dev/lirc to the pertinent /dev/input/event* (but don't) when I run:
  $ sudo restart udev

  ...but they do produce "permission denied" errors when I run:
  $ udevadm test $(udevadm info -q path -n /dev/input/event3)
  (assuming it's event3 today)

  ...however running as root creates the symlink just fine:
  $ sudo udevadm test $(udevadm info -q path -n /dev/input/event3)

  They are however picked up as the same udevadm output reads:
  "udev_rules_apply_to_event: LINK 'lirc' /etc/udev/rules.d/10-local.rules:1"

  BTW, This rule should do effectively the same thing but fails silently, presumably for the same permissioning reason:
  KERNEL=="event*",ATTRS{vendor}=="0x14f1",RUN+="sudo ln -fs /dev/input/%k /dev/lirc"

  I've applied a workaround by hacking /etc/init.d/lirc as per
  http://www.mythtv.org/wiki/LIRC#Troubleshooting but it's frightfully
  inelegant.  Would like to get the udev rule working
