The way I read it, the part in capitals grabs all the attention and
breaks the flow of the main sentence. When I first read it (admittedly
not carefully enough) I thought it meant "Installing this version of
udev will break the system at next reboot. It will do this by creating
the /etc/udev/kernel-upgrade file." :)
I think it would have been much clearer if it had been:
AT YOUR OWN RISK, you can force the installation of this version of
udev, by creating the /etc/udev/kernel-upgrade file. However, this
version of udev does not work with your running kernel, so, after
upgrading udev, you MUST also upgrade the kernel before rebooting.
OTHERWISE YOU WILL BREAK YOUR SYSTEM AT THE NEXT REBOOT.
