Can you say "filesystem labels"? I thought so.

I can say it won't fix an existing configuration. I can say that filesystem label creation wasn't well thought out for people that move disks around (after you've installed fedora on all your machines, they'll all have the same labels and the system is not happy when you rebuild a machine with a different combination of drives). I can say that the design of solaris seems to take machine management over long intervals of time and large numbers of machines into consideration whereas Linux does not.

- or turns what used to be detected as eth0 into eth2 when a different kernel is booted?

echo -e "alias eth0 module1\nalias eth2 module2\n" >> /etc/modprobe.conf
has always worked for me.

That worked in 2.4 kernels. It doesn't with udev based kernels. And if you managed some number of machines with multiple interfaces you'd probably care - especially if they are remote and you lose access when the network doesn't come up after a reboot.

Have you filed a bug?

Is it a bug or is udev supposed to detect devices in parallel and dynamically (randomly)? It is the same with /dev/sdX devices. How do I know which one is /dev/sdh today? And If I don't know, even If I wanted to use filesystem labels, what would I call the device when I wanted to create the label? (BTW, what I usually do to work around this issue is create an md raid device even if it is a single drive with a missing partner and use the md device name in the fstab entry because at least so far I have been able to count on consistency in detecting the uuids and have always gotten unique ones by default).
