$ ls -l /usr/lib/debug/.build-id/fa/841219472d35412ad631ad0f0fabb78e5c1957.debug
lrwxrwxrwx 1 root root 27 2007-10-21 15:58 /usr/lib/debug/.build-id/fa/841219472d35412ad631ad0f0fabb78e5c1957.debug -> ../../lib64/ld-2.7.so.debug*
tells the name of the already installed library missing its -debuginfo.

$ repoquery -qf /usr/lib/debug/.build-id/fa/841219472d35412ad631ad0f0fabb78e5c1957.debug
glibc-debuginfo-0:2.7-2.x86_64
tells the -debuginfo package name needing to be installed.

# yum install /usr/lib/debug/.build-id/fa/841219472d35412ad631ad0f0fabb78e5c1957.debug
installs the missing -debuginfo package.

The library name was omitted intentionally there as the printed lines are
already too long just to be able to provide the .debug filename required for
`yum install'.

People commonly try to debug with GDB without having the -debuginfo packages
installed so I expected some hint may be useful there.

`debuginfo-install <appname>' may not install the matching -debuginfo version,
there may be multiple simultaneous -debuginfo versions available and/or
installed in the future (F9?).

I am open for some more convenient interface - currently going to print also
the shared library name there.  (GDB cannot print anything about rpms.)


Thanks,
Jan
