/dev/hd* gone with udev

["Jason Dunsmore" <jasondunsmore@gmail.com>]

I recently upgraded my Debian testing system.  When I rebooted, almost
all the device nodes in /dev were gone, and the system wouldn't boot
all the way up (got all the way to starting nfs, somehow).

I ended up removing udev and installing hotplug through the
single-user recovery console.  I'd like to go back to udev when I get
this figured out because I've written some custom rules.  Other people
have had a similar problem, but no solution was found:

I tried downgrading to udev 0.100-1, a version I know worked, but I
saw the same problem.

Could it be my configuration?  My /etc/udev/rules.d/local.rules file
contains the following:

SYSFS{model}="5VLAT80", NAME{all_partitions}="usb_hd"
SYSFS{model}="iFP Mass Driver", NAME{all_partitions}="iriver"
SYSFS{model}="Flash Voyager", NAME{all_partitions}="key_drv"
SYSFS{model}="Cruzer Micro", NAME{all_partitions}="key_drv"
SYSFS{model}="USB to IDE Card", NAME{all_partitions}="cf_card"

Thanks.
