To toggle at boottime, use different runlevels. 1 that mounts tmpfs over /dev and starts udev. Another that doesn't. And /dev contains static device nodes. -- Joost -- Sent from my Android device with K-9 Mail. Please excuse my brevity.

It would probably be asking for too much to try to toggle between udev and static /dev at boot time in a single installation... I remember that it was possible to toggle before openrc was introduced. As things stand now, you would probably have to replace sys-fs/udev with sys-fs/static-dev (which satisfies virtual/dev-manager). NeddySeagoon mentions it here: http://dev.gentoo.org/~neddyseagoon/Old_Fashioned_Gentoo_2.xml He also describes its coverage as being incomplete. In that case, this may help to populate /dev to a reasonable extent: https://bugs.gentoo.org/show_bug.cgi?id=368597#c97 --Kerin
