How the branding works

To add a new theme, add a new Theme section to etc/config. Example for theme SLES:

[Theme SLES]
image             = 600		# memory limit for loading inst-sys: 600 MB
patch_zypp_config = 0		# whether to adjust zypp.conf for micro-os-like systems
# other entries are branding prefixes or suffixes to branding-related packages
release           = sles	# sles-release.rpm
skelcd            = sles	# skelcd-sles.rpm
skelcd_ctrl       = SLES	# skelcd-control-SLES.rpm
gfxboot           = SLE		# gfxboot-branding-SLE.rpm
grub2             = SLE		# grub2-branding-SLE.rpm
plymouth          = SLE		# plymouth-branding-SLE.rpm
systemd           = SLE		# systemd-presets-branding-SLE.rpm

Then add an appropriate theme section to installation-images.spec.

Note that the actual product name and path for driver updates are auto-generated from /usr/lib/os-release. For completely new products you'll have to adjust lib/ReadConfig.pm::get_version_info and please also leave a sample of the os-release file in etc/os_sample.txt.
