I'm building on the system I wish to update. The system itself is 13.0-CURRENT (r356092) and based on gcc 4.2.1. I was going to initially try a live update, but I wasn't sure how successful that would be (but this is a VM so I'd be able to rollback without difficulty). If that didn't work out, I was going to try and create some bootable media and install a new instance from that. I have currently allocated 32GB of memory and there appears to be about 3G of swap and 32 threads. The physical host is a Talos II (so POWER9) running Linux/KVM/libvirt.
