@docorange6 Sorry for the late answer.
Looking at the information you posted we see that it handles sda2 (SWAP as we see from type=82) as fixed partition. And because of that I am fairly sure it will resize the boot partition (sda1) back to it’s original size as well.
I can understand that you would prefer it to not touch sda1 at all and I think we have fixed this in the latest scripts already. Please download the latest init files (32 bit and 64 bit) and put those into /var/www/html/fog/service/ipxe/ (best to rename the original ones instead of directly overwriting those.
