- I've been told that the VMS POSIX.1 implementation simply
- creates a large VMS file in which a POSIX.1-compliant file
- system can be built, and thus creates a limited sandbox in
- which POSIX.1 programs can run. I can understand why an
- implementation of RCS running in such an environment would
- be less than ideal; it wouldn't be able to manage files in
- the VMS file system.

- If this is to change, it'll have to be because government
- users buy into the POSIX philosophy and demand systems that
- support POSIX functionality as a fully capable operating
- system interface. I don't know whether the right place to
- express this demand is in the FIPS that mandates POSIX or
- in the specifications of the individual procurement. I
- lean toward the latter, because it's difficult to require
- that systems "do the right thing" and still (a) be fair to
- all vendors and (b) give the government agencies enough
- leeway to procure the products they need.
-
- The public comment period on the proposed FIPS 151-2
- ended a week ago, so if you disagree with my opinion
- you've just missed an excellent opportunity to influence
- US government policy on the issue.
