- I am in full agreement that a SUBSET of "mail" and "lp" (or "lpr")
- interfaces should be standardized, just not the whole package (for
- instance, definitely NOT the interactive mail-reading interface).
- My command-set proposal to 1003.2 contained several such cases of
- limited subsets of what was in the SVID. I view 1003.2 primarily
- as a collections of tools for use by application programs, not as
- things a naive user would confront directly.

-
- There is little value in restricting the 1003 standards to lowest-
- common denominator subsets of existing UNIX implementations, since
- many interesting and useful applications simply cannot be written
- to work well within such a limited subset. Consequently, the 1003.1
- trial-use standard already differs in several (relatively minor, we
- hope) ways from existing UNIX systems. POSIX conformance will require
- a certain amount of change to existing systems. We've been working
- fairly closely with AT&T SVID people on this issue, in an attempt to
- ensure that a system can be simultaneously SVID and POSIX compliant
- without requiring separate "universes" (libraries, etc.).
-
- As one of the original separate-universe implementors, I wish to
- state that any such implementation should be viewed as an interim
- measure while we attempt to converge on a single universal standard.
- (I believe this is what Sun is attempting to do.) It will sure be
- nice to be able to quit worrying about annoying trivial system
- variations and get to work on better applications.
