A vmx image is the same disk as an oem just without the dracut
repart/resize feature. This difference is better handled with
an oemconfig parameter <oem-resize> which allows to switch resize
on or off. The extra image type vmx will be dropped and an XSLT
stylesheet automatically transforms a vmx description to be a
oem image with the resize feature switched off.
This Fixes#1425
KIS is an abbreviation for Kernel, Initrd, System and defines a
highly customizable image consisting out of these components.
This commit performs the changes documented in #1414 and
introduces the new kis type. From an image build perspective
kis is currently the same as pxe with restrictions for kis
on the schema level. A kis build uses dracut and does not allow
to use the legacy netboot initrd. The pxe type will therefore be
exclusively used to built for the legacy netboot infrastructure
and is on its way to deprecation in the future.
This Fixes#1262
