What is /etc/udev/links.conf?

Hi,

I would like to know what /etc/udev/links.conf is?

Thank you in advance!

The rules for device naming, are read from the files located in the /etc/udev/rules.d/ directory, or at the location specified by the udev_rules value in the /etc/udev/udev.conf file.
Every line in the rules file defines the mapping between device attributes and the device name. One or more keys are specified to match a rule with the current device. If all keys are matching, the rule will be applied and the name is used to name the device file or the network interface.
If no matching rule is found, the default kernel device name is used.

I know what udev is but what does /etc/udev/links.conf actually for?

this old udev bug seems to explain it (near the bottom). relevant portion below:

+# The content of this file is read by the /etc/init.d/udev script to
+# create custom device entries, directories and symbolic links in the
+# /dev/ directory.
+# Usage of this file is at your own risk and strongly discouraged since
+# it works around the udev daemon which normally creates such entries.
