You are upgrading from version 3.2.2 of base-passwd which had a nasty
bug: it swapped the uid and gid of local accounts.  If you have not
fixed this problem manually I can undo the changes by restoring your
previous passwd file from the backup /etc/passwd.org.

update-passwd has found some differences between your system accounts
and the current Debian defaults.  It is advisable to allow update-passwd
to change your system; without those changes some packages might not work
correctly.  For more documentation on the Debian account policies, please
see /usr/share/doc/base-passwd/README.

The list of proposed changes is:

EOF

		cat $tmp
		cat <<EOF

It is highly recommended that you allow update-passwd to make these changes
(a backup file of modified files is made with the extension .org so you can
always restore the current settings).

		cat <<EOF

Okay, I will not update your system.  If you want to make this update later
please check the update-passwd utility.
