... ahem, you keep saying that (no need for /etc/passwd) to me :-)) However, my
(personal) bin
directory has a script called mkpasswd_r(edacted) ... that modifies the uid of
some of my users
(yes, me, and a few aliases for me).
And I am sure, that I am not the only one with a script like that ...
Above you are explaining _implementation_ ... not specification.

As you will observe, in the 'old days', mkpasswd -l defaulted to 'mkpasswd'.
As it does for the test release, in case one removes /etc/nsswitch.conf.

(in fact 'mkpasswd -l <my machine>' now shows the same output as the above
commands do)
However, in case "nsswitch.conf" specifies passwd: files
mkpasswd and mkpasswd -l are NOT equal anymore # as result of the
_implementation_
This change in behaviour is not apparent from 'mkpasswd --help' ... and it is
not documented anywhere.
Yes, I know, that you modified the _implementation_ in response to a request by
Christian Franke, and
I do not object against change, but change should not confuse ... I believe.
Bottom-line: the kludge you introduced in mkpasswd (at the request of C.)
backfired (well, it did to me).
