Without exec, the processes from the new shell do not get a ctty:
root@intel-corei7-64:~# ps -x | grep getty
755 tty1 Ss+ 0:00 /sbin/getty 38400 tty1
791 ? Ss 0:00 /bin/sh /bin/start_getty 115200 ttyS0
804 ? S 0:00 grep getty
In particular, the openssh client fails:
root@intel-corei7-64:~# ssh -v <target>
<truncated>
debug1: read_passphrase: can't open /dev/tty: No such device or address
Host key verification failed.
This patch fixes those errors.
