Bump.
This is the current content of the ros.attr file, if it helps:
%__ros_provides %{_rpmconfigdir}/ros.prov
%{?__filter_GLIBC_PRIVATE:--filter-private}
%__ros_requires %{_rpmconfigdir}/ros.req
%{?__filter_GLIBC_PRIVATE:--filter-private}
%__ros_path ^/usr/lib.*/ros/.*$
%__ros_magic ^(setuid,? )?(setgid,? )?(sticky )?ELF (32|64)-bit.*$
%__ros_flags exeonly,magic_and_path
%__elf_exclude_path %__ros_path
Is the last line acceptable? If not, how else can I exclude the ROS
directory (%__ros_path) from being scanned by the ELF dependency generator?
