Trying to do a clean install of 17.7.5 amd64 via USB memory stick on an OPNsense Quad Core Gen3 rack appliance (4GB RAM, 2GB CF), and it fails around 77%:
Execution of the command
/usr/local/bin/cpdup -vvv -I -o /usr/share /mnt/usr/share
FAILED with a return code of 1.

Searching the forums I found:
[WONTFIX] Boot media for 15.1.9 : error 1 at installation.

Is this the same cpdup / memory exhaustion problem, and is there anything I can do to salvage this unit? As it has aborted mid-install it no longer boots from the CF. It was running 17.1.4 just fine prior to this.
UPDATE / SOLVED!
Choosing MBR instead of GPT got it working.
