This PR establishes a baseline for the oldest *BSD releases supported by Bitcoin Core. Clarifying these minimum requirements paves the way for dropping compatibility code and workarounds for unsupported versions.
The obsolete FreeBSD-specific workaround and version check have been dropped.
This change establishes a baseline for the oldest *BSD releases

Have we any tests or nightly builds running on NetBSD 9.x?
Have we any tests or nightly builds running on NetBSD 9.x?
Not in https://github.com/hebasto/bitcoin-core-nightly.
It was dropped in https://github.com/hebasto/bitcoin-core-nightly/pull/236:
With NetBSD 11 approaching, it is reasonable to drop support for 9.x. Currently, the 9.4 package repository is still linked to
2025Q4rather than2026Q1.
Not sure why, but NetBSD 9.4 doesn't seem to be booting sometimes? (https://github.com/bitcoin-core/libmultiprocess/actions/runs/28966971473/job/85952515522#step:3:211):

Given that 10 is already out and presumably support will be dropped for 9 once 11 is out, it seems fine to drop support for it?
