Thanks @grahamperrin. Do you know what the solution would be?

[grahamperrin]

If the module is already loaded or in kernel, then do the linked parts of overlays/uzip/hello/files/etc/rc.d/load_acpi (loading the module) make sense?

[probonopd]

The question is, how can we find out whether the module is already loaded (and why) or in the kernel?

[grahamperrin]

(and why)

Try debug.verbose_sysinit=1 in loader.conf(5).

freebsd/freebsd-src@c796240

Postscript: that'll not work in distributions that are based on STABLE or RELEASE.

freebsd/freebsd-src@be352d2 … turned off in stable branches …, so no VERBOSE_SYSINIT in releng/13.0 at https://github.com/freebsd/freebsd-src/blob/releng/13.0/sys/amd64/conf/GENERIC, and so on.

I don't see this with an installation of experimental-14.0-0.8.0_0H77:
