I don't know when you used BSD last, but the FreeBSD libc SONAME hasn't changed in years (maybe a decade?). All symbols are versioned and backwards compatibility is maintained with quite old versions of FreeBSD libc when APIs change. E.g., https://github.com/freebsd/freebsd/blob/master/lib/libc/g... . (FreeBSD 7 is from 2008.)

That’s FreeBSD, not BSD ;-)

A bit more seriously, FreeBSD “feels” like trying to imitate what GNU/Linux does, just a bit behind the times and selectively. They also do a lot of rewrites (one could say NIH) and are very removed from the other BSDs (even the two active forks of it), code-wise.

Yeah, this was OpenBSD I think. What's their libc soname up to now... libc.so.92, good grief.
