Argh. Again.

I wonder if they finally made this true. This sentence has been in the
output for a long time now, but I believe it was false; if it's now
true, then that might break the ... no, wait. That's not it. The rule
uses IMPORT{program} instead.
But this is it:

(From /lib/udev/rules.d/75-persistent-net-generator.rules.)
Let me ensure this works on my real-hardware machine (running kernel
3.2.2 and udev-180 now, but still a pretty old glibc, so maybe not a
perfect test, but hopefully close)...
Yeah, it works. Moving the existing 70-persistent-net.rules file out of
the way (to root's home directory) and running a manual "udevadm test
--action=add /sys/class/net/eth0" generates a file with almost the same
rules in it. (The new file matches on ATTR{dev_id} while the old one
did not.)
Of course, the comments are totally wrong; it thinks the device ID is
the devpath, since network devices have a "device" symlink, whereas the
sysfs attribute containing the device ID for PCI devices is also named
"device", and udev matches on the child first -- I don't see how to fix
this in the rules. :-(
Also, I see this output in the middle:
udev_rules_apply_to_event: IMPORT builtin 'pci-db'
/lib/udev/rules.d/75-net-description.rules:11
Failed to open database file 'no': No such file or directory
Looks like either the --with-pci-ids-path=no flag isn't doing what we
expect, or the 75-net-description.rules file is not being correctly
suppressed. It doesn't hurt anything, but it'd be nice to be able to
kill this. (And it seems that the net-description rules file pulls in a
lot more than just the PCI and USB device databases, as well, so we
can't just delete it. Looks like the default udev rules do something
similar for TTYs (probably usb-serial) and sound cards, as well. Fun fun.)
