+Notes on setuid
+===============
+
+For a correct functionality depending on the host OS, you need
+to run the equivalent of these steps after installation.
+Replace $(DESTDIR)$(libexecdir) with the appropriate paths,
+for example /usr/local/lib/gnunet/libexec/. Note that this
+obviously must be run as priviledged user.
+
+chown root:root $(DESTDIR)$(libexecdir)/gnunet-helper-vpn
+chmod u+s $(DESTDIR)$(libexecdir)/gnunet-helper-vpn
+chown root:root $(DESTDIR)$(libexecdir)/gnunet-helper-transport-wlan
+chmod u+s $(DESTDIR)$(libexecdir)/gnunet-helper-transport-wlan
+chown root:root $(DESTDIR)$(libexecdir)/gnunet-helper-transport-bluetooth
+chmod u+s $(DESTDIR)$(libexecdir)/gnunet-helper-transport-bluetooth
+chown root $(DESTDIR)$(libexecdir)/gnunet-helper-dns
+chgrp $(GNUNETDNS_GROUP) $(DESTDIR)$(libexecdir)/gnunet-helper-dns
+chmod 4750 $(DESTDIR)$(libexecdir)/gnunet-helper-dns
+chgrp $(GNUNETDNS_GROUP) $(DESTDIR)$(libexecdir)/gnunet-helper-dns
+chown gnunet:$(GNUNETDNS_GROUP) $(DESTDIR)$(libexecdir)/gnunet-helper-dns
+chmod 2750 $(DESTDIR)$(libexecdir)/gnunet-helper-dns
+chown root:root $(DESTDIR)$(libexecdir)/gnunet-helper-exit
+chmod u+s $(DESTDIR)$(libexecdir)/gnunet-helper-exit
+chown root:root $(DESTDIR)$(libexecdir)/gnunet-helper-nat-server
+chown root:root $(DESTDIR)$(libexecdir)/gnunet-helper-nat-client
+chmod u+s $(DESTDIR)$(libexecdir)/gnunet-helper-nat-server
+chmod u+s $(DESTDIR)$(libexecdir)/gnunet-helper-nat-client

+
+Scope of Operating System support
+=================================
+
+We actively support GNUnet on a broad range of Free Software Operating
+Systems.
+
+For proprietary Operating Systems, like for example Microsoft Windows
+or Apple OS X, we accept patches if they don't break anything for
+other Operating Systems.
+If you are implementing support for a proprietary Operating System,
+you should be aware that progress in our codebase could break
+functionality on your OS and cause unpredicted behavior we can
+not test. However, we do not break support on Operating Systems
+with malicious intent.
+Regressions which do occur on these Operating Systems are 3rd
+class issues and we expect users and developers of these
+Operating Systems to send proposed patches to fix regressions.
+
+For more information about our stand on some of the motivating
+points here, read the 'Philosophy' Chapter of our handbook.
