RaidSonic NAS-4220 telnet root login without password

another bug I found in the software of the NAS-4220-B is that you can use telnet to login to the NAS-4220-B as root without being ask for as password. This is possible right after boot of the device. The problem seems to originate from the fact that the software puts together the filesystem in ram during boot. The actual bug is that telnetd is started before /etc/passwd is populated with a root account that has a password set.
