Checkinstall has been dropped from openSUSE because it doesn't work
anymore. Checkinstall's trick is to load a library via LD_PRELOAD that
redirects all functions dealing with files. Now for installing a package
you need to be root and for programs running with root privileges the
dynamic loader ignores LD_PRELOAD as this would otherwise be a huge
security problem.

The behaviour is: For programs being setuid root, LD_PRELOAD is ignored
- or more exactly:
/* The LD_PRELOAD environment variable gives list of libraries
separated by white space or colons that are loaded before the
executable's dependencies and prepended to the global scope
list. If the binary is running setuid all elements
containing a '/' are ignored since it is insecure. */
