[arch-dev-public] Old udev install/upgrade message

[Dan McGee]

ATTENTION UDEV:
----------
udev >=098 rules syntax has changed, please update your own rules.
udev >=099 Added persistent network and CD/DVD Symlink generator rules.
Please read the instructions carefully before reboot.
They are located in /etc/udev/readme-udev-arch.txt
----------
warning: /etc/udev/rules.d/udev.rules saved as
/etc/udev/rules.d/udev.rules.pacsave
(33/37) upgrading udev                              [---------------------] 100%


Can't we kill this super old message from udev install? Or at the very
least, make it conditional? When useless messages are shown, people
tend to ignore all messages.
