Bug#501849: Please permit installation with an empty user password
Package: user-setup
Version: 1.23
Severity: wishlist
Tags: patch
User: ubuntu-devel@lists.ubuntu.com
Usertags: origin-ubuntu intrepid ubuntu-patch
When performing an install, the user cannot proceed without entering a
non-empty password. This remains the case even when an empty password
has been specifically preseeded.
For most use cases, this is clearly entirely the correct behaviour. In
those rare cases where someone really, really, wants to have an empty
password for an automatically created user, it would be nice if
user-setup would allow this directly, rather than requiring workarounds
such as reset with late_command.
The attached patch creates an additional internal-use-only preseed
boolean: passwd/allow-password-empty which when set to true allows the
use of an empty password, either interactively or through preseeding.
Users will still be asked for a password, but will not be forced to
enter one.
I've created the patch against revision 56349 in SVN, but would be happy
to update it to a newer revision with modifications if requested.
