Package: gnunet-server
Version: 0.9.3-2
The gnunet-helper-fs-publish binary is provided set-UID root by
the package, which (as per upstream, see below) is unnecessary.
Apart from raising security concerns, it also precludes
gnunet-publish(1) from running when GNUnet itself runs under an
“ordinary” user (as opposed to a dedicated, “system” one.)
My reading of debian/gnunet-server.postinst (as of b3ea4f34,
quoted below) is that the issue is likely to be present in the
yet unreleased 0.9.3-4 version of the package.

91 chown root:${_GROUPNAME} $file
92 chmod 4754 $file
93 fi
94 done

Could this please be rectified? TIA.
