Since Red Hat 6.0, iBCS has been included as a module, but the binfmt-322 has not been included in the default module configuration. This was not the case through 5.2. This causes previous SCO users to be seemingly unable to run their programs "out of the box" as they had been able to. I get a lot of complaints on this one. This also tends to make businesses migrating from SCO->Linux a little nervous for some reason, so it should probably be fixed. Since the solutions are simple to impliment, it's obviously low priority, but I feel it should still be addressed. If you're going to include the module yet, please enable it as it had been all through the 5.x series.
this appears to be fixed at this point.
