# offset 1S => 1 sector (1x512 byte)
# The bootloader can be at 5 different position: 1S, 34S, 4096S, 8192S, 12288S
# MBR disk use only the sector 0, so 1S is free
# GPT disk use sector 0-33S, so first free slot is 34S

# Current bootloader is about 1.8MB, so if we put it at 4096S and 12288S we
# have 4MiB between the first bootloader and the second copy of it

# Don't name partition in the installer disk image, otherwise the installer may not work as it rely on partition label!
