[Adduser-devel] Bug#630643: adduser: Cancelling with Ctrl+C still adds entries to /etc/{passwd, group}

[jamon]

Package: adduser
Version: 3.112+nmu2
Severity: normal

Cancelling adduser part way through the creation of a new user results in entries being written to /etc/passwd and /etc/group.

This behaviour is a) not what is normally expected when using Ctrl+C to cancel a command, and b) results in a potentially unconfigured but still existant user and group on a system.

The script should be modified to only write to passwd/group files *after* a user confirms with 'Y'.
