Ah, OK.

Fedora 36: 3.10.5
Ubuntu 20.04: 3.8.10
Debian 11: 3.9.2
OpenSUSE Leap 15.4 uses 3.6.15, but 3.9 and 3.10 are available with a
simple zypper invocation.
CentOS Stream 8 uses 3.6.8, but 3.8 and 3.9 are available.
CentOS Stream 9 uses 3.9.13.
Alpine: Not sure, but tests pass.
FreeBSD 12: 3.7 (tests/vm/freebsd already uses this version.)
OpenBSD: ?
NetBSD: ?

I can update the commit message, but I do have questions for you in
patch 5 concerning the docker configurations and our test matrix that
I want to work out before a respin.
