Minimal static dev entries?
As I moved my data from one disk to another (well actually from a disk to an md device) I used cp -ax which stays ona given filesystem, and thus I never get static /dev entries on my new root device.
The only things that seem to be needed by the static boot prior to udev being started (i.e the only things to cause error) were /dev/console and /dev/null. So I made these two and the system now boots fine and udev gets started and in /dev/.static/dev I have console, null, and a named pipe called initctl.
So my question is... is there anything else that _should_ be in the static dev filesystem that's needed until udev get's started? udev is started extraordinarily early in the boot process, so I don't suspect so, but I thought I'd ask those who know best.
Thanks,

No, in my experience the only entries needed are /dev/console and /dev/null.

It all depends on your distro and its startup logic. Some don't need any static nodes :)
thanks,
