Unexpected behaviour you saw

MKOSI generates the image correctly. But when booting the image from USB I see the following error messages, before the login prompt shows up. The OS, however, works correctly. GRUBerrormessage_1

The error messages are coming from /grub/grub.cfg, which I attached as 'MKOSI Output' below. It looks like the 'if statement' causing the issue. When I change the 'if statement' as below, it seems to work. No error messages. if [ "${grub_platform}" == "efi" -o test "${grub_platform}" == "pc" ]; then
