we can't do anything until things are stabled. and since you haven't said what you think needs to be changed, we really can't do anything!
Comment 2 Samuli Suominen (RETIRED) gentoo-dev 2013-01-27 09:15:23 UTC
udev-197-r3 is now stable, and you can find information from the ebuild's postinst messages and the released news item

(the .rules referenced live in /etc/udev/rules.d)

- enable CONFIG_DEVTMPFS
- make sure you have "/dev" line in /etc/fstab saying 'devtmpfs' as fstype, and no, I don't mean "/dev/shm" or anything like that, I mean /dev exactly
- remove 70-persistent-cd.rules if you haven't edited it
- remove 70-persistent-net.rules if you haven't edited it
- remove udev-postmount from runlevels
- remove 80-net-name-slot.rules if you want the new networking name scheme
- separate /usr works fine with sys-fs/udev-197, just like it did for 171
- support for older kernels than 2.6.39 has been removed. anyone needing newer   kernel is supposed to go sys-fs/eudev -- this is the only reason for eudev at the moment
- if you have sys-apps/biosdevname installed, emerge -C it if you want the new networking scheme, and propably otherwise too if you don't really use it, to avoid conflicts
- make sure /run exists, udev's ebuild creates it in postinstall, then boot is recommended for this

so... here is some info for udev guide...

please feel free to contact me at Freenode if you need more info about some of the items listed
Comment 4 Adam Feldman gentoo-dev 2013-02-13 21:14:08 UTC
Don't forget CONFIG_DEVTMPFS_MOUNT=y too
Comment 5 Sven Vermeulen (RETIRED) gentoo-dev 2013-02-18 17:13:56 UTC
Is the CONFIG_DEVTMPFS_MOUNT=y needed? I have it enabled, but I'm not sure it is needed

> it is needed

DEVTMPFS is needed, but DEVTMPFS_MOUNT is optional, the init script handles it if it's missing
Comment 7 Benny Pedersen 2013-03-08 05:22:20 UTC
DEVTMPFS_MOUNT is needed to have smp working, so its only needed if smp is awail, dont know if its just my computer, but its needed here, else it would just boot one cpu

i dont really know why, but i like to share it here
Comment 8 Sven Vermeulen (RETIRED) gentoo-dev 2013-04-06 11:39:33 UTC
Most changes were already made in the last months' updates. I'll just drop the mention of 2.6 kernels for this one.
