Thanks for all the suggestions. I did the following, which worked. |
| 40 |
|
| 41 |
1. Built and installed kernel with CONFIG_DEVTMPFS=y |
| 42 |
|
| 43 |
2. Moved udev-postmount back to /etc/init.d (I had moved it to /tmp). |
| 44 |
rc-update add udev-postmount default. |
| 45 |
3. Reboot with new kernel (udev unchanged). Success. |
| 46 |
|
| 47 |
4. Changed NAME=eth0 to NAME=net0 in 70-persistent-net.rules and |
| 48 |
eliminated clauses so have only (on one line) |
| 49 |
SUBSYSTEM=="net", ACTION=="add", ATTR{address}=="00:1e:c9:48:f9:a0", |
| 50 |
NAME="net0" |
| 51 |
Corresponding changes to /etc/init.d /etc/runlevels/default |
| 52 |
|
| 53 |
5. Emerge update world to get new udev (just -1 udev has blocks) |
| 54 |
|
| 55 |
6. Change kernel configs as per udisks emerge output |
| 56 |
|
| 57 |
7. /usr/lib/udev already empty (due to make world?) so nothing to do |
| 58 |
|
| 59 |
8. Reboot with new kernel. Success |
| 60 |
