Hi, |

*Problem:* |
| 4 |
I have a number of hosts spread around the country running the 2.6.12 |
| 5 |
kernel. I need to upgrade to 2.6.18, which requires udev to replace |
| 6 |
devfs. Is there any way I can prepare /dev for this upgrade so the hosts |
| 7 |
will boot without human interaction/booting with CD-ROM? |
| 8 |
|

*Details:* |
| 10 |
When I previously upgraded my own laptop a year or so ago, this led to |
| 11 |
the lack of certain dev-nodes upon boot (/dev/console and /dev/null, I |
| 12 |
believe), causing a kernel panic. I fixed that by booting with cd-rom |
| 13 |
and recreating the necessary nodes, as described in section 3 here: |

| 15 |
|
| 16 |
This is of unfortunately not an option for my hosts since the majority |
| 17 |
don't run any form of LOM, and getting a tech to stand by each host, |
| 18 |
boot the Rescue-CD and do all sorts of stuff is a major hassle. |

*Possible solution:* |
| 21 |
I think a possible solution may be to do the following while the host is |
| 22 |
still running its old kernel: |
| 23 |
|
| 24 |
mount --bind / /mnt/point |
| 25 |
cd /mnt/point/dev |
| 26 |
mknod -m 660 console c 5 1 |
| 27 |
mknod -m 660 null c 1 3 |
| 28 |
cd / |
| 29 |
umount /mnt/point |
| 30 |
|
| 31 |
Will/should this work? If not: Any other suggestions? |
| 32 |
|
| 33 |
Cheers, |
