Old programs in the linux a.out format won't run on newly installed redhat 6.0 systems. Work around is to find the old redhat 5.2 cdroms and install the aout-libs-1.4-9.i386.rpm and insmod the binfmt_aout module. Can the aout-libs-1.4-9.i386.rpm be included on future redhat releases?
No. If aout compatibility is needed, do as suggested - use the RPMs from 5.2.
