I thin this exists in both -STABLE and -CURRENT, but I don't have a
bang up to date instalation of either, so appologies if it has been
fixed.
Tested on 5.2.1 and 4.8. may have some security implications in that
someone may think they have changed a shell (eg to /nonexistant) but
they haven't really.
Apparently, supplying -d EXITING_HOME_DIR stops -s from setting the
shell.
# finger fred
Login: fred Name: Fred Flintstone
Directory: /home/fred Shell: /usr/local/bin/bash

No Mail.
No Plan.
# pw usermod fred -s /bin/sh -d /home/fred
# finger fred
Login: fred Name: Fred Flintstone
Directory: /home/fred Shell: /usr/local/bin/bash
Never logged in.
No Mail.
No Plan.
(ie no change)
# pw usermod fred -s /bin/sh
# finger fred
Login: fred Name: Fred Flintstone
Directory: /home/fred Shell: /bin/sh
Never logged in.
No Mail.
No Plan.
(now we have changed)
# pw usermod fred -s /usr/local/bin/bash -d /home/fred2
pw: WARNING: home `/home/fred2' does not exist
# finger fred
Login: fred Name: Fred Flintstone
Directory: /home/fred2 Shell: /usr/local/bin/bash
Never logged in.
No Mail.
No Plan.
(ie setting a different home allows the shell to change)
Looks like an over-enthusiastic `if' in the code to me.
