+  * sendmail, debian/control, debian/rules, debian/lsb-invalid-mta.dirs:
+    Added new binary package "lsb-invalid-mta" containing a fake
+    /usr/bin/sendmail so that the installation of LSB packages does not
+    pull in an MTA any more, which once adds awkward configuration questions
+    to the installation process and second adds an often unnneeded daemon to
+    the system (LP: #141641).
+
+  * debian/control: The LSB requires the printing environment already
+    since version 3.2. Made lsb-printing required by the "lsb" package
+    not only suggested (LP: #386128).

+Description: Linux Standard Base sendmail dummy
+ The Linux Standard Base (http://www.linuxbase.org/) is a standard
+ core system that third-party applications written for Linux can
+ depend upon.
+ .
+ This package contains nothing else than a fake /usr/bin/sendmail
+ command to fulfill the LSB's requirement of providing this command without
+ requiring an MTA to get installed, which once introduces a daemon which
+ can cause security problems and second, users get asked questions about
+ how they want their MTA configured when in reality they simply wanted to
+ install a deskltop application or a printer driver, but the dependency on
+ LSB compliance pulls in an MTA with the installation.
+ .
+ The LSB requirement on /usr/bin/sendmail comes from old times where Linux
+ and Unix machines had all fixed IPs and did server tasks in data centers.
+ Today's typical desktop Linux machines do not do local e-mail any more as
+ users use external e-mail services.
+ .
+ The /usr/bin/sendmail always exits with exit status -1 (255) and sends a
+ warning message to stderr, so that if a program actually tries to send e-mail 
+ via the sendmail command the user gets note.
