So what need to happen? rpcdebug tool is being installed in the nfs-utils.spec %install section: install -s -m 755 tools/rpcdebug/rpcdebug $RPM_BUILD_ROOT/usr/sbin The '-s' option causes the binary to be stripped of debugging information during the install. Please remove the '-s' option there. reproduced on nfs-utils-1.2.3-7.el6: .live.[root@x86-64-6s-m1 ~]# rpm -qa|grep nfs-utils nfs-utils-1.2.3-7.el6.x86_64 nfs-utils-lib-devel-1.1.5-3.el6.x86_64 nfs-utils-lib-1.1.5-3.el6.x86_64 nfs-utils-lib-debuginfo-1.1.5-3.el6.x86_64 .live.[root@x86-64-6s-m1 ~]# eu-readelf --notes /usr/sbin/rpcdebug Note section [ 2] '.note.ABI-tag' of 32 bytes at offset 0x21c: Owner Data size Type GNU 16 VERSION OS: Linux, ABI: 2.6.18 Note section [ 3] '.note.gnu.build-id' of 36 bytes at offset 0x23c: Owner Data size Type GNU 20 GNU_BUILD_ID Build ID: 16550087196a3eba2cfb1fcc2b6cfc5ae2bcd7d5 .live.[root@x86-64-6s-m1 ~]# ls -la /usr/lib/debug/.build-id/16/550087196a3eba2cfb1fcc2b6cfc5ae2bcd7d5 ls: cannot access /usr/lib/debug/.build-id/16/550087196a3eba2cfb1fcc2b6cfc5ae2bcd7d5: No such file or directory verified on nfs-utils-1.2.3-12.el6: [root@hp-xw4550-01 ~]# eu-readelf --notes /usr/sbin/rpcdebug Note section [ 2] '.note.ABI-tag' of 32 bytes at offset 0x148: Owner Data size Type GNU 16 VERSION OS: Linux, ABI: 2.6.18 Note section [ 3] '.note.gnu.build-id' of 36 bytes at offset 0x168: Owner Data size Type GNU 20 GNU_BUILD_ID Build ID: 1181c7750458b71c1c4421887dd40c2bc2de9c9a [root@hp-xw4550-01 ~]# ls -l /usr/lib/debug/.build-id/11/81c7750458b71c1c4421887dd40c2bc2de9c9a lrwxrwxrwx. 1 root root 25 10月 9 03:05 /usr/lib/debug/.build-id/11/81c7750458b71c1c4421887dd40c2bc2de9c9a -> ../../../../sbin/rpcdebug and do code review to check the '-s' option had been removed in the nfs-utils.spec %install section: install -m 755 tools/rpcdebug/rpcdebug $RPM_BUILD_ROOT/usr/sbin Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.
