UDEV upgrade some links
2013-01-23-udev-upgrade Title Upgrading udev from 171 (or older) to 197 Author Samuli Suominen <ssuominen@gentoo.org> Posted 2013-01-23 Revision 1 Upgrading udev from 171 (or older) to 197 will require special attention: - Remove udev-postmount from runlevels. - The need of CONFIG_DEVTMPFS=y in the kernel; need to verify the fstype for possible /dev line in /etc/fstab is devtmpfs (and not, for example, tmpfs) - The case of predictable network interface names; if the file /etc/udev/rules.d/70-persistent-net.rules is being used for renaming network interface names to already existing names, then you need to read following bug[1] because it's no longer possible. This won't be a problem with the new predictable network interface name scheme[2]. [1] http://bugs.gentoo.org/453494 [2] http://www.freedesktop.org/wiki/Software/systemd/ PredictableNetworkInterfaceNames - Support for older kernels than 2.6.39 is dropped. If you need older kernel we recommend you to look into sys-fs/eudev or use local overlay for keeping the old ebuild. Remember to also get the distfiles where the patchsets are. The upgrade into current stable version of gentoo-sources is recommended. - The case of separate /usr; if it worked for you with 171 it will continue to work for you with 197. We still recommend initramfs with separate /usr mounting capabilities because you might need packages like sys-apps/kbd (keymaps in /usr) or net-wireless/bluez (possible keyboard) in early boot. And read every message printed by the emerge of udev and udev-init-scripts to ensure the system is in order before booting as this news item might not be complete. Apologies if this news came too late for you.
