reason not to do so, was my lazines while debugging this stuff ;)
the problem is, that if kannel starts in daemon mode then _all_ paths
(binary/config/config includes/etc) _must_ be absolute. We can easy check
for binary path and config path within utils.c context, but can't check
e.g. config includes because the whole idea of parachute/daemon is, to be
transparent to all kannel binaries.
We must call chdir("/") because e.g. if kannel starts w/o changing CWD and
this directory is a mounted one, then admin can't unmount this volume w/o
stopping kannel.
