RE: [lsb-futures] Supporting multiple LSB runtimes

I think the obvious is to say that

1) Any version will suport all previous versions with the same major
number, ie 1.2 will provide 1.1 and 1.0.
2) Any major version should not (but can if necessary) break
compatibility with the previous major, ie 2.9 *should* provide 1.0, but
may break it if there are good reasons.
3) Further back than this - don't chance your arm ie 3.0 has no
obligation to provide any 1.x release.

Cheers,
Wol

Subject: [lsb-futures] Supporting multiple LSB runtimes

Hi lsb-discuss and lsb-futures,

AJ Towns and I had a discussion about how Debian is going to implement
an LSB 
2.0 runtime. We had some thoughts that have implications for LSB
upstream and 
other runtimes. Here's what we came up with.

Requirements
============
1.) Runtime implementations need to be able to support more than one
  version at a time to allow for applications that need the different
  versions. Example: LSB 1.2, 1.3 and 2.0
2.) Currently runtime support for a version of the LSB implies support
  for all previous versions, and applications can count on that.
  Example: you should be able to run a 1.2 application on a 1.3 system
