I replaced the /etc directory with the one we are using on the production machines... by the way. What can be wrong? When it starts init , and execute the /etc/rc.d/rc.sysinit , it is hell slow. We have tried replace /sbin/init with bash and we got out a shell but "ls -l" takes more than 2 minutes... do you know what sort of settings in the /etc will affect use space "bash" or "glibc" on nfsroot behaves different ? This is so strange.
Thanks
