As long as Sun does not break compatibility, certifying for S8 should
pretty much guarantee that it works on S9, S10, and S11 (whenever that's
released).

That doesn't matter to some vendors. There are many that will only
support you if you are running the version (and patch set) that they say
will work. There's alot of software like this.

Actually, the only reason for having solaris 8 was that I was still
using one. (A 280R, with 4 1 GHz CPUs.) But since I don't actually use
that machine anymore, Solaris 10 is fine.

Thanks to you and everyone else for the pointers to containers. That's
probably more work than I want to do.

Just fyi, containers are VERY easy to setup (in case somebody wonders).

True, Synopsys is one that has S9 as supported platform for all EDA
tools and S10 is supported in "compatibility" mode which must mean that
if it runs in S9 and breaks on S10 S10 is still supported without
leaving the S9 in the dust.
