 Posted: Tue Sep 09, 2014 11:31 pm Post subject: Update udev from 171 to 215 [SOLVED] |
 |
|
I've recently resurrected and old Gentoo (stable AMD64) system that hadn't had any updates for almost a year. Over the last several days I have finally gotten everything updated to the point where I have a clean 'emerge -uDN @world' and revdep-rebuild is happy. I am now ready to give it a reboot, but I am concerned about the udev upgrade. I can't say exactly which version I updated from, but based on the udev tarballs in distfiles I would say it was from version 171. Current installed version is 215-r1.
So I have gone through everything in the upgrade guide on the gentoo wiki (http://wiki.gentoo.org/wiki/Udev/upgrade). But there are a few lingering doubts in my mind.
| Quote: | | If there is a /dev line in /etc/fstab, it must have the devtmpfs filesystem type or it will conflict with the above options |
There is a '/dev' line for every partition in my fstab, like always. Filesystems include ext2, ext3, and reiserfs. Am I really supposed to change all those to devtmpfs? That doesn't sound right?
I have rolled a new kernel (3.14.14), because my understanding is that my old kernel will not boot with the new udev.
I have:
| Code: |
CONFIG_BLK_DEV_BSG=y
CONFIG_DEVTMPFS=y
CONFIG_FHANDLE=y
CONFIG_DMIID=y
# CONFIG_IDE is not set
|
in it.
I have replaced /etc/init.d/net.eth0 with net.enp0s8.
Anything else I'm forgetting? Again, I'm just concerned because my understanding is my old kernel won't boot with the new udev if I've missed something, and I really don't want to deal with an unbootable system.
Thanks...

That isn't the /dev they are referring to. The wiki is literally referring to a line like | Code: | | devtmpfs /dev devtmpfs mode=0755,nosuid 0 0 |
If you don't have one you shouldn't need it. Also, if udev fails to work properly you shouldn't be completely up a creek.

Partially correct. Udev wouldn't work, but I think you would still get to a rescue shell. Assuming you started with a clean .config and added your drivers then you should be fine. If you used make oldconfig then you are probably fine, but large jumps could be a problem.
The only other consideration I can think of is if /usr is a separate partition. If it is you will want to take steps. If not, I think shutdown -r now is about the only way to know if you did everything right. I'd keep a System Rescue CD handy, but then I always do.

That is what I thought, thank you. Just wanted some clarification.
My /usr is part of /, so no problem there.
I'm going to give it a go, wish me luck ha ha ha...

Booted like a champ, even the networking works. Thanks again...
