Reporting that the rpi4 arm64.aarch64 is still running ok.

I did however encounter a similar error with an amd64-based bhyve vm. This vm
is unmodified
in comparison to the arm64.aarch64 device. It runs 13.0-p5 and updates via
freebsd-update. The symptoms were a bit different though, in that:

1. the script ran without error

2. no services were accessible. No ping, smtp, nothing, from anywhere. (this is
the best failure mode honestly. The worst nightmare would be
not-to-load-leaving-everything-open). I checked the tables for blocked IPs and
made sure my accessing IP wasn't listed and it wasn't.

3. on reboot, services didn't come back. I had to access via the console. I was
able to bring services back by disabling pf, updating the ruleset then
re-enabling it.

maybe this would need a different ticket & diags
