Package: sane-utils
Version: 1.1.1-2
Debian includes a "scanner" group when the operating system is
installed. When installing the sane-utils package, the newly-created
"saned" user is added to this group by default. If the sane-utils
package is purged though, the "scanner" group is deleted along with the
"saned" user. This should not happen, since the group does not belong to
SANE.
Attempting to install the sane-utils package again will actually fail
during configuration, because the "saned" user cannot be added to the
"scanner" group which no longer exists. (Although this is the default
behavior, a debconf question asks if the "saned" user should be added to
this group.)
