I agree completely.  This, and the implementation of ulimit(2), lead
me to wonder what AT&T were thinking of when they created S5.  I've
been trying for three months to convert from V7 to S5;  so far the only
advantages I can see in S5 are:

    1)	Greatly improved print spool mechanism (this is indeed a big win)
    2)	It's a "standard"

Against this must be balanced:

    1)	Above-mentioned bug (yes, bug) in mv
    2)	ulimit (ok, the idea isn't so bad, but the implementation is wrong)
    3)	adb is missing
    4)	dbm is missing
    5)	It's bigger and slower
    6)	The uucp node name is COMPILED into the kernel!

If it weren't for the impending arrival (S5R3) of streams and RFS,
I'd be tempted to give up, buy a source license, and back-port the print
spool stuff to V7.

Although I suspect the reasons are political and not technical, I wonder
if anyone at AT&T (or anyone else who thinks they know the real story)
could comment on why so much in S5 is missing and/or wrong.
