Solved freebsd-update : modified files issue

How would I go about solving this issue?

I don't have the original sshd_config file.

$ sudo freebsd-update fetch
Looking up mirrors... 3 mirrors found.
Fetching metadata signature for 13.2-RELEASE from done.
Fetching metadata index... done.
Inspecting system... done.
Preparing to download files... done.
The following files are affected by updates. No changes have
been downloaded, however, because the files have been modified

No updates needed to update system to 13.2-RELEASE-p5.
I usually just rename /etc/ssh/sshd_config to /etc/ssh/sshd_config.saved, then do the freebsd-update fetch and install.
When the update is one, change the filename back to /etc/ssh/sshd_config

I have no idea whether this is the-right-way to do it, but this method does seem to work reliably.
