freebsd-update odd output

Hi,

On arm64, updated via freebsd-update like 14.4 -> 14.5 > 15.1 and
during the 15.1 stage, when updating userland, the following 
output was displayed:

src component not installed, skipped
Installing updates...install: ///var/db/etcupdate/current/etc: No such file or directory
install: ///var/db/etcupdate/current/etc/devd: No such file or directory
install: ///var/db/etcupdate/current/etc/devd: No such file or directory
install: ///var/db/etcupdate/current/etc: No such file or directory

install: ///var/db/etcupdate/current/etc/rc.d: No such file or directory
install: ///var/db/etcupdate/current/etc/rc.d: No such file or directory

Restarting sshd after upgrade

Just wondered if it's anything I need to worry about.
The machine seems to be running fine.

The machine is an rpi3b running unbound (from pkg-ports) and not much
else.
