[gentoo-user] udev-197: what to do

[Allan Gottlieb <gottlieb@nyu.edu>]

I have read the news item and still have questions.  The news item
covers several points.

1. remove udev-postmount:
   I did this but worry that I now cannot reboot until I upgrade
   udev.  Is that correct?

2. Add CONFIG_DEVTMPFS=y.  Easy.  Kernel rebuilt and installed
   in /boot (but have not rebooted).

3. Predictable network interface names.
   I have the problematic udev rule.
   Specifically 70-persistent-net.rules has (on one line)

   SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*",
   ATTR{address}=="00:1e:c9:48:f9:a0", ATTR{type}=="1",
   KERNEL=="eth*", NAME="eth0"

   I read the bug report, but it is not as clear as I would like.
   Is it true that I can change my file to simply

   SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*",
   ATTR{address}=="00:1e:c9:48:f9:a0", ATTR{type}=="1",
   KERNEL=="eth*", NAME="net0"

   That is just change the NAME from eth0 to net0 ?

4. No support for kernels older than 2.6.39.  No problem.

5. Separate /usr not affected.  Good.

The news item does not mention the problem of moving files
from /usr/lib/udev/rules.d to /lib/udev/rules.d.  Am I correct in
believing that we still need one of the equivalents of
   equery belongs -n /usr/lib/udev | xargs emerge -pv

I used that successfully when one of my testing systems went to
udev-197.  I would think it is needed (before reboot) on my stable
systems as well so I am surprised it is not in the news item.

thanks,
