If it's a problem with glibc, doing "chroot /mnt/sysimage" will not
work, because that will use the messed up glibc on the system.

Instead, use the --root argument to rpm.  This will use the working rpm
and glibc binaries from the rescue environment to run rpm, but will
check the databases and file system of the installed system.  For
example:

	rpm --root /mnt/sysimage-q --queryformat
	'%{NAME}-%{VERSION}-%{RELEASE}-%{ARCH}\n' glibc kernel
(that should all be on one line)

That command uses a custom query format to show the architecture of the
installed RPMs as well as the name, version, and release.  A common
problem is to install an i386 version of glibc where an i686 or athlon
kernel with NPTL is being used; they are not compatible.
