Bug#401925: Not replacing /etc/default/saslauthd renders daemon unable to start.

[Ka Teznik]

package:sasl2-bin
version:2.1.22.dfsg1-5
severity:normal

During a dist-upgrade, i got the following error :

Paramétrage de sasl2-bin (2.1.22.dfsg1-5) ...
Fichier de configuration « /etc/default/saslauthd »
 ==> Modifié (par vous ou par un script) depuis l'installation.
 ==> Le distributeur du paquet a fourni une version mise à jour.
   Que voulez-vous faire ? Vos options sont les suivantes :
    Y ou I  : installer la version du responsable du paquet
    N ou O  : garder votre version actuellement installée
      D     : afficher les différences entre les versions
      Z     : suspendre ce processus pour examiner la situation
 L'action par défaut garde votre version actuelle.
*** saslauthd (Y/I/N/O/D/Z) [défaut=N] ? n
Installation de la nouvelle version du fichier de 
configuration /etc/init.d/saslauthd ...
Starting SASL Authentication Daemon: saslauthd/usr/sbin/saslauthd: option 
requires an argument -- n
usage: saslauthd [options]

option information:
  -a <authmech>  Selects the authentication mechanism to use.
  -c             Enable credential caching.
  -d             Debugging (don't detach from tty, implies -V)
  -r             Combine the realm with the login before passing to 
authentication mechanism
                 Ex. login: "foo" realm: "bar" will get passed as login: 
"foo at bar"
                 The realm name is passed untouched.
  -O <option>    Optional argument to pass to the authentication
                 mechanism.
  -l             Disable accept() locking. Increases performance, but
                 may not be compatible with some operating systems.
  -m <path>      Alternate path for the saslauthd working directory,
                 must be absolute.
  -n <procs>     Number of worker processes to create.
  -s <kilobytes> Size of the credential cache (in kilobytes)
  -t <seconds>   Timeout for items in the credential cache (in seconds)
  -v             Display version information and available mechs
  -V             Enable verbose logging
  -h             Display this message.

saslauthd 2.1.22
authentication mechanisms: sasldb getpwent kerberos5 pam rimap shadow ldap

Due to the heavy differences (in comments) between the two files, I choose n, 
then saslauthd refused to load. 

Modifying START=yes in the new file corrected the problem.
A message inciting to modify the conffile, and saving the old one instead of 
rewriting it should IMHO be used.
