Title:
shadowconfig uses "pwck -p" and "grpck -p" which aren't actually
supported
Status in shadow package in Ubuntu:
Fix Released
Status in shadow package in Debian:
Fix Released
Bug description:
/sbin/shadowconfig from the passwd package uses "pwck -p" and "grpck
-p". On some other Linux systems, the -p flag to these programs says
to silently fix problems found in those files.
But the Ubuntu Lucid versions do not actually do that. The Ubuntu
Lucid versions ignore the -p option, and then go ahead and prompt for
confirmation before making changes.
This can be dangerous at install time. If the install image has
problems in the group or passwd files (for example, mention of an
unknown user in the group file), then finish-install's postinst will
call 06user-setup, which calls user-setup-apply, which calls
shadowconfig. When that prompts for input, the install will hang.
This with passwd version 1:4.1.4.2-1ubuntu2.2, which includes
shadowconfig, grpck, and pwck.
