Anyone wanting to lock the root account (not a good idea IMHO) should

was no longer possible in new sessions.
In the worst case, couldn't someone just boot from a livecd, run
[passwd root], then [cat /etc/shadow | grep root] on the livecd and
finally simply copying that entry into the locked out system shadow
Sure but this involves bringing the system down. If you don't allow the
three fingered salute on the console to reboot or halt the system then it
involves bringing the system down badly. If we are talking of a
production system this is a _very bad thing_ even after hours.
