It will depend on the Linux distribution that you are using. If the 
distribution puts the udev files in udev's default location, then they 
udev rules will be in /etc/udev/rules.d and the binaries and scripts 
called by the udev rules will be in /lib/udev. In addition, scripts 
called by udev are sometimes put in /etc/udev/scripts.

If the udev rules file name has not been changed from the original 
MythTV contribution, then it will be called mythtv.rules. Looking 
inside, you can see what script file is called. However, if the name of 
the script has not been changed from the original MythTV contribution, 
then it will be called mythtv_udev_monitor.sh.

Inside mythtv_udev_monitor.sh, you will see a conditional that sends the 
appropriate information to the FIFO. You could wrap another conditional 
around this that tests the DEVNAME and does not continue when the 
DEVNAME is the device that you want to exclude.

Having said that, basing things on the device name can be problematic. 
There is no absolute assurance that a device will always have the same 
name unless something special is done in the udev rules to ensure it. As 
a result, you are better off using labels, GUIDs or something else 
unique to identify the device. In MiniMyth, if the partition has the 
label minimyth, then I exclude it.
