Keywords: ULIMIT did not become tunable until SysV.3.1 - FAR too late

      My impression is that what is being discussed is the variable
   ULIMIT which is the maximum write size of a file.  If so, then DO
   NOT mess with init.  In SYS V version 2.something and later ULIMIT
   is a TUNABLE parameter.

The max-file-size-limit is exactly what that script is supposed to
fix.  In fact, that limit did not become a tunable until (*cringe*)
SysV.3.1; I have a SysV.3.0 3B2/400 called osu-cis which does not have
any reference to ULIMIT in its /etc/master.d/kernel.

The script I posted is something I wrote 2 years ago when fighting
this problem every time I turned around (I am in the habit of having
to move very large files around with quite some frequency), and I
formalized it for myself and also sent it to Richard Stallman for
inclusion in the standard GNU Emacs distribution when I was doing SysV
compatibility things for that program; I picked up the copy I posted
here from just such a distribution.  Although it is quite tunable in
The Right Way via /etc/master.d files in V.3.1, it took AT&T
altogether TOO LONG to figure this out, and in fact it was ridiculous
of them to have ever imposed the stupid 1Mb limit in the first place.

So if you have V.3.1, please ignore the script I posted.  If, however,
you are one of the vast, VAST majority of non-AT&T sites (and thus
cannot get V.3.1 practically for free) running V.3.0 or V.2.x.y.z.a.b,
then that script will do a very nice job of "fixing" your ulimit
problems.
