I find the problem still persists Please see the last leg of the logs below *eth0: link up (100/Full)* *VFS: Mounted root (nfs filesystem) on device 0:12.* *Freeing init memory: 128K* *Starting network...* *ip: RTNETLINK answers: File exists* *Starting dropbear sshd: OK* * * I feel the already generated key has been detected. And still the initab doesn't execute.
