Hi all,

 just in case even if I have the sensation that it is too weird to be
integrated in ISAR. :-)

Subject: [PATCH] dpkg.bbclass runs ldconfig and create s.chmod at chroot
setup

dpkg.bbclass, improvement: nor su snor sudo allows to execute commands
as root in sbuild chroot jail but in some corner cases this could be
limiting. For this reason a s.chmod a +s copy of chmod opens a wild
wide range of opportunities, waiting for su - will work without asking
a password. Trying to run it, it seems that a lack of ldconfig exists.
So, the first command that runs at chroot setup is ldconfig by now.
