SUSE Distro Names / Base Products

Sample code using libzypp:

zypp::Target_Ptr target = zypp::getZYpp()->target();
zypp::Product::constPtr product = target->baseProduct();

logDebug() << "Product name: " << product->name()
           << " summary: "     << product->summary()

YaST gets community repos from a link in /control.xml on the installation medium or at /etc/YaST/control.xml in the installed system:

Linux Kernel Firmware Packages

Motivation

Kernel firmware packages consume a lot of disk space on a Linux system, both on the installed system and in an installation environment (inst-sys). In some cases (e.g. RAM disk for a minimal NET ISO), that also means a lot of RAM usage.

Invoking External Commands in YaST

Best Practice: Yast::Execute

This is the method to use since about 2018. Don't use SCR .target.bash in new code.

	The workaround for this was to set LD_PRELOAD if libsuseconnect.so was
	found, but that causes new problems: This is inherited by child
	processes, and now every binary started from YaST also gets this
	LD_PRELOAD, so they are now also force linked to libsuseconnect.so.

	YaST uses external programs extensively; among lots of other things,
	for storage probing. That means that in many cases, storage probing
	now fails because of this; mostly due to out of memory because
	libsuseconnect.so (and the Go runtime libs that it uses?) consumes a
	lot more RAM.
