+
+Yes. Because while debugging a program in RHEL or Fedora, a command
+named 'debuginfo-install' which is provided by yum-utils can be used
+to automatically install all needed debug information packages. For
+example, to install the debuginfo package of bash:
+
+#debuginfo-install bash
+Loaded plugins: fastestmirror, refresh-packagekit, remove-with-leaves
+enabling epel-debuginfo
+Loading mirror speeds from cached hostfile
+ * base: mirrors.btte.net
+ * epel: ftp.riken.jp
+ * epel-debuginfo: ftp.riken.jp
+ * extras: mirrors.btte.net
+ * nux-dextop: mirror.li.nux.ro
+ * updates: mirrors.163.com
+Checking for new repos for mirrors
+Could not find debuginfo pkg for dependency package

+Is this ok [y/N]:
+
+
+For developer and Testing Engineer, the easier to obtain full debug
+information about a package, the easier to find out defects or bugs.
+
+Besides the debuginfo package, I think the kexec package is important
+to generate a vmcore if the kernel panic occurs. I repackage the
+kexec-tools of Mandriva for Mageia and currently testing on my laptop.
+
+BTW, the gdb in the mageia2 still cannot tell which debug packages
+should be installed while debugging. And it seems that the work-around
+~~~
+https://bugs.mageia.org/show_bug.cgi?id=3417#c19
+~~~
+does not works...
+
+Should I recompile the latest gdb package on Mageia to make it work?
+
+Many thanks!!
