Recently, another mkpasswd related problem popped up: seems that on
(some?) Slackware boxes, mkpasswd does not support -m <method>, and
buildroot fails. See
Making sure we always use the same mkpasswd would help in both cases.
Should we create a separate host-mkpasswd package based on the whois
Or should we add the whois package, and depend on that?
To me, the former seems more appropriate...
