Please forgive me if I posted this in the wrong category. My immediate task isn't related to P2P, but my end goal of setting up a personal server is. I am attempting to compile a custom image with https://github.com/botter-nidnul/userpatches. You can read more about the project here https://urbit.org/grants/urbian-a-customized-linux-distribution-for-urbit-appliances. I can compile a focal image without customization, but when I attempt to customize the image, I get `umount: /home/nebulay/repo/project/armbian/build/.tmp/rootfs-d412f0e4-e33c-4c0c-909b-9042f7924589: target is busy` This repeats until I hit ctrl+c. I get an image, but it fails to boot. I have googled it, and this is the only somewhat useful thing I've found https://github.com/armbian/build/issues/1472 which doesn't help me much. Does anyone have any ideas on how compile the image or what could be causing the problem?
