Hey C.L. Martinez, This is because grub-bhyve creates memory mappings that are both writable and executable, something that is disallowed by default on HardenedBSD. You'll need to add a secadm rule to disable pageexec and mprotect restrictions for grub-bhyve. You can find a sample rule here: https://github.com/HardenedBSD/secadm-rules/blob/master/grub-bhyve.rule Thanks, -- Shawn Webb Cofounder and Security Engineer HardenedBSD GPG Key ID: 0x6A84658F52456EEE GPG Key Fingerprint: 2ABA B6BD EF6A F486 BE89 3D9E 6A84 658F 5245 6EEE
