Description

I’ve tried to boot a USB image built from feature/15292-usb-image, both on bare metal and in a VM, and I see “This is not a bootable disk. Please insert a bootable floppy and press any key to try again …”. I guess one of the recent commits aimed at fixing reproducibility or GUIDs broke it.

Fixed by 95a33f55dec4e4e66760a1df9c88deb2a2a4a62f. It was broken because syslinux was installed while the system partition was mounted. I don’t know why this breaks things and didn’t investigate.

Thanks a lot for the quick fix! :) I’ll take a look today or first thing tomorrow.

Yeah, I’m not surprised that having two parties (syslinux and the vfat kernel driver) competing for concurrent write access to the same block device leads to “interesting” outcomes. Not worth investigating IMO.

Code review passes and I confirm that the resulting image is bootable again :)
