[Message part 1 (text/plain, inline)]

Package: eudev
Version: 3.2.7-5
Severity: normal

The eudev init script names it's pid file udev.pid and causes a false
positive in rkhunter:

Warning: Checking for possible rootkit files and directories [ Warning ]
         Found file '/var/run/udev.pid'. Possible rootkit: xorddos component

Changing the init file to use the pid name of eudev.pid fixes the
problem.
