As someone who uses Linux to develop commercial code on, and LSB as a means
of being able to support many distributions with one binary, that's what
I understood when I took up using LSB nine years ago. It has done this job
very effectively so far, and our answer when asked 'do you support FooLinux?'
is simply '"run lsb_release -a" and e-mail us the response', and if that says
LSB 3.1 or later, then we'll support it.
I have the advantage that my product is a mathematical modelling library,
with no user interface, just an API. That makes it very easy to produce with
If LSB didn't exist, we'd only support one or two distributions, because the
overhead of QA on more would not be commercially viable. While I'm much less
savvy on Linux politics than most people here, the continued existence of so
*many* Linux distributions does seem to indicate that there isn't a great
demand for Linux unification. Unification would be *really useful* for
commercial application vendors, because for many of them the fragmentation
of the market promises lots of overhead in customer support, far more than
they'll make in sales.

Thanks for that: it saved us a load of trouble.
