chroot -- success?
Looks as if I spoke too soon. (Too many brandies.)
Having checked that "pwd" returned "/" for one test user in a test
directory, I set up the passwd files for six others, logged off,
re-booted -- and found myself back to square one. !!?!!
And now I don't know exactly what it was I did to make it work.
(all files have retained the same settings -- so it must have been an
ephemeral system change caused by my constant reconfigurations; and it
had something to do with changing the configuration of pam. Which now
appears to be totally ineffective.)
Back to the keyboard.
