In 10 years your five machines will be easily outclassed by a single machine costing a fraction as much, if Moore's Law holds up. In fact, by then you could probably virtualize all five onto the same platform and still come out ahead. Might I suggest that your best option is not to look for an OS which has a 10-year release lifetime; something I think you'ld struggle to find from any FOSS project, and would probably have to pay exhorbitantly for from a commercial provider. Instead, look for an OS where you can maintain a configuration environment for the lifetime of your project. By that I mean you can still run the original binaries. In this respect, I think FreeBSD would be one of the better choices. I mean, 10 years ago, FreeBSD 5.0 and 5.1 were the latest releases. Now, that release branch had its problems, but it marked the last hugely incompatible change across major version updates (as seen in the 3 -> 4 and 4 -> 5 upgrades). In principle, given a suitable set of compat5x libraries (ie. the misc/compat5x port) and a kernel compiled with 'options COMPAT_FREEBSD5' (which is in the default kernel), you could run software compiled for 5.x on a contemporary system. Of course, there can't be any guarantees that your project running on FreeBSD 9.2 now could be supported in compat9x mode on FreeBSD 15.x in 2023. But I'd suggest the FreeBSD is probably one of your best bets for achieving that. Cheers, Matthew --=20 Dr Matthew J Seaman MA, D.Phil.
