1. card-part: This type of scripts create partitions on the card as the
bootloaders expect them. This type of scripts are necessary only for
machines whose board support layer still builds images in 'old style'
e.g rootfs as *.tar.bz2).
2. card-write: These type of scripts write complete images (bootloader/
machines whose board support layer still builds images in 'old-school'
way e.g rootfs as *.tar.bz2).
2. card-write: This type of scripts write complete images (bootloader/
devicetrees/kernel/rootfs) onto card.
Machine defaults can be overriden by setting variables
'Machine' / 'FindString' - see include/card-helpers.inc
function StartCardWrite.
3. card-kernel-write: This family of scripts just overwrite kernel, devicetrees
and kernel modules on cards with image installed. These scripts are extremly
helpful for testing kernel/devicetree modififations or just updating kernel
on precious (=many settings applied / full of userdata) images.

To reduce the GUI-dialogs displayed or avoid them completely all scripts can be

3. su / sudo selection: Pass '1' for su or '2' for sudo
