I can't make it to QUITE ten years.
I can, if you want to include commercial unixes. At my last job we had a
binary only source control db that was originally made for HP-UX 6. It
still worked on HPUX11. Impressive really.
I want to get a /bin/ls from Solaris 2.0 circa Jul. 92, and run it on a
Solaris 10 circa Jan 2005 just to see if it will work. That is when Sun
went from BSD to SVR4. Supposedly, backward compatibility was one of the
key features.
actually, the early solaris 2.X (aka SunOs 5.X) systems did NOT have
binary-compatibility with SunOs 4.X systems (aka solaris 1.X). it was
only added later, due to customers demands.
it was also not fully compatible - we once stumbled across a "bug" in
the compatibility layer (i think it was on solaris 2.5.1. don't remember
if it had to do with handling signals, or with handling errno values -
but it was in one of those).
