I think binary configuration files requiring specialized editors weren't all that popular. We had a RS6000 box in the lab, originally acquired to assure compatibility of our enterprise NAS appliance with AIX. Nobody liked that box and as Linux won the Unix wars, we were relieved that we didn't have to deal with it. (and yes, while Linux was then the (much) preferred choice, we had prior experience with other *nixes)
