This was a fundamental piece of the design of UNIX and was inherited by many UNIX derived systems. While debugging System IV systematizing, we had meetings with the folks from Murray Hill and they insisted that this had to be maintained. (circa 1982)
The actual details of what has broken are not as important as the fact that the breakage happened and complaints about the breakage have be dismissed with disrespect and disparaging remarks about clinging to ancient history. That has been done at least twice in this set of threads. Certainly, Linux is an evolving and growing system, but there seems to be no natural selection process to cull the things that don't work. Change is NOT the problem, without change there can be no progress. But to change something for no good reason, simply to change it, is not healthy. -- G.Wolfe Woodbury [email protected]
