===Using Atomic Updates With the System Role Transactional Server=== | === Using Atomic Updates With the System Role Transactional Server === | ||
The installer supports the system role ''Transactional Server''. This system role features an update system that applies updates atomically (as a single operation) and makes them easy to revert should that become necessary. These features are based on the package management tools that all other SUSE and openSUSE distributions also rely on. This means that the vast majority of RPM packages that work with other system roles of openSUSE Leap 15.2 also work with the system role ''Transactional Server''. | The installer supports the system role ''Transactional Server''.

The installer will only propose a partitioning scheme if the available hard disk size is larger than 12 GB. If you want to set up, for example, very small virtual machines images, use the guided partitioner to tune partitioning parameters manually. | The installer will only propose a partitioning scheme if the available hard disk size is larger than 12 GB.

Prior to installing openSUSE on a system that boots using UEFI (Unified Extensible Firmware Interface), you are urgently advised to check for any firmware updates the hardware vendor recommends and, if available, to install such an update.

openSUSE minimizes the risk by not writing more than the bare minimum required to boot the OS. The minimum means telling the UEFI firmware about the location of the openSUSE boot loader. Upstream Linux kernel features that use the UEFI storage area for storing boot and crash information (<code>pstore</code>) have been disabled by default. Nevertheless, it is recommended to install any firmware updates the hardware vendor recommends. | openSUSE minimizes the risk by not writing more than the bare minimum required to boot the OS.

Together with the EFI/UEFI specification, a new style of partitioning arrived: GPT (GUID Partition Table). This new schema uses globally unique identifiers (128-bit values displayed in 32 hexadecimal digits) to identify devices and partition types. | Together with the EFI/UEFI specification, a new style of partitioning arrived: GPT (GUID Partition Table).

Updating from KDE 4 and Qt 4 to Plasma 5 and Qt 5 is recommended. KDE 4 and Qt 4 are no longer supported. openSUSE Leap 15.2 still contains KDE 4 and Qt 4 packages for compatibility reasons. However these packages will no longer receive updates and security fixes. Therefore it is strongly recommended to replace all installed KDE 4 and Qt 4 packages with packages from Plasma 5 and Qt 5 providing the same or at least similar functionalities. | Updating from KDE 4 and Qt 4 to Plasma 5 and Qt 5 is recommended.
