The problem is handling upgrades between two different major revisions
of a distribution. e.g. Debian 3.1 shipped udev 56 and kernel 2.6.8,
while Debian 4.0 shipped udev 105 and kernel 2.6.18.
udev 105 did not work with kernel 2.6.18 and udev 56 did not work with
kernel 2.6.8, so the udev installation script had to jump hoops to not
start the new udev, make sure that a suitable updated kernel was
installed at the same time and recommend the administrator to reboot
ASAP.
And if for some reason the new kernel does not work, the user will be
left with a mostly broken (no working udev) system.
This is why I would really really like to see kernel 2.6.26 supported by
udev for the next few years.
