ahh. Sorry. For example, I am using the RELEASE version of FreeBSD 12
https://download.freebsd.org/ftp/releases/arm64/aarch64/ISO-IMAGES/12.0/ <https://download.freebsd.org/ftp/releases/arm64/aarch64/ISO-IMAGES/12.0/>

Im installing the image on a microsd card, install my software and configurations.
I do not install ports nor kernel source since I do not intend to rebuild everything.

Question: using this setup can I re-create the image or like you said can I just
then add my own software and configurations (few) on top of the generic ARMv8
image (this would probable be the simplest way ?)

Thanks a lot,
Stefan
