Detection of how the command is supposed to behave actually depends on the configure.h compilation and whether binary is compiled with HAVE_BLKID_SUBLKS_FSINFO. This makes it somewhat complicated in a way how to recognize which behavior is expected. Currently we can eventually recognize by checking error output of some 'random' lvresize command and see if the --fs checksize is actually recognized and rejected. If this changes - test needs to be updated.
