Went through this trying to boot tinycore detached signed iso.
To replicate on recovery shell:
- put Tinycore iso on usb thumb drive (this is isolinux, not grub)
usb-init #select iso (will fail since iso is not detached signed)
mount -o remount,rw /media #put media in write mode
gpg --card-status #to map public key and security dongle's private key
gpg --detach-sign /media/tinycore.iso #to sign iso
mount -o remount,ro /media #to sync changes to media, putting in in read only mode
usb-init #to mount usb media to media, search iso and mount to /boot, and search /boot for boot options
This will pass detached signature validation, but will fail to find bootable options.
