Init hanging

Sun Mar 19 12:41:12 UTC 2006

Hi Vadi,

I'll bet that you have used the buildroot utility to build your rootfile 
system, linked your NFS to that directory and are trying to boot 
directly from that root directory...

Buildroot is using fakeroot to make the device nodes (files in /dev/), 
but they are really seen as ordinary files.

Run makedevs as root (in the proper directory) will solve that problem.

(I send a post on busybox-mailinglist the 20. february "Re: Boot 
problems with NFS")
