[Pkg-shadow-devel] Bug#471667: Bug#471667: Bug#471667: [D-I] Configuration of passwd during debootstrap fails when run in non-clean target

[Justin Pryzby]

clone 471667 -1
reassign -1 base-passwd
retitle -1 base-passwd: update-passwd leaves account files in inconsistent state according to pwck (should remove user with low UID from shadow, too)
found -1 3.5.17
thanks

I assumed it was just trying to read from a closed FD (perhaps not due
to dpkg not providing one in general, but IDK what your installation
environment is, and guessed that it didn't provide a stdin).

Do you know what version libuuid was initially installed?  I suspect
one of the problems was fixed in libuuid1 1.40.7-1 (See #466929).  If
you agree, the initial report (#471667) can be closed.

I changed my mind about the passwd pwck -q prompting problem.  On
rereading the manual page, the description isn't that it avoids
prompting, but rather inhibits report of warnings (errors still cause
prompts).

That leaves one remaining problem (plus excessive configuration
attempts by dpkg): base-passwd leaves the account files in a state
where pwck later fails.  base-passwd should also have removed the
relevant line from /etc/shadow.
