The 15 branch says:

hostname = neoemma
uname -m = x86_64
uname -r = 6.2.8-100.fc36.x86_64
uname -s = Linux
uname -v = #1 SMP PREEMPT_DYNAMIC Wed Mar 22 19:14:19 UTC 2023

So at least the kernel claims to be 36...

Yea, I was thinking yesterday that we should add uname output to meson's
configure (if available). I'm sure we can figure out a reasonably fast windows
command for the version, too.

Could also be filesystem specific?
