I know. I did research about that but gave up.
This is how I solved my problem for now: <https://github.com/BertramScharpf/rbfind/commit/e6ed59668cb5707f4519272401113a8173f819af>.

Bug #21205: File::Stat#birthtime is available on Linux
https://bugs.ruby-lang.org/issues/21205#change-112497
* Author: BertramScharpf (Bertram Scharpf)
* Status: Open
* ruby -v: ruby 3.3.7 (2025-01-15 revision be31f993d7) [x86_64-linux]
* Backport: 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN, 3.4: UNKNOWN
----------------------------------------
Not that I would run into any problem with it, but this behaviour is confusing:
RbConfig::CONFIG["platform"] #=> "amd64-freebsd14"
(File.birthtime "/").class #=> Time
(File.stat "/").birthtime.class #=> Time
RbConfig::CONFIG["platform"] #=> "x86_64-linux"
(File.birthtime "/").class #=> Time
(File.stat "/").birthtime # raises NotImplementedError
