	Using Atomic Updates With the System Role <emphasis>Transactional Server</emphasis>
	The installer supports the system role <emphasis>Transactional Server</emphasis>. 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 15.4 also work with the system role <emphasis>Transactional Server</emphasis>.
	Incompatible Packages
	Some packages modify the contents of <filename>/var</filename> or <filename>/srv</filename> in their RPM <literal>%post</literal> scripts. These packages are incompatible. If you find such a package, file a bug report.
	To provide these features, this update system relies on:
	Btrfs snapshots
	Before a system update is started, a new Btrfs snapshot of the root file system is created. Then, all the changes from the update are installed into that Btrfs snapshot. To complete the update, you can then restart the system into the new snapshot.
	To revert the update, simply boot from the previous snapshot instead.
	A read-only root file system	Programiškai prijunkite pradinę šakninę rinkmenų sistemą:
	To avoid issues with and data loss because of updates, the root file system must not be written to otherwise. Therefore, the root file system is mounted read-only during normal operation.
	To make this setup work, two additional changes to the file system needed to be made: To allow writing user configuration in <filename>/etc</filename>, this directory is automatically configured to use OverlayFS. <filename>/var</filename> is now a separate subvolume which can be written to by processes.
	<emphasis>Transactional Server</emphasis> Needs At Least 12 GB of Disk Space
	The system role <emphasis>Transactional Server</emphasis> needs a disk size of at least 12 GB to accommodate Btrfs snapshots.
	YaST Does Not Work Transactional Mode
	Currently, YaST does not work with transactional updates. This is because YaST performs things immediately and because it cannot edit a read-only filesystem.
	To work with transactional updates, always use the command <command>transactional-update</command> instead of YaST and Zypper for all software management:
	Update the system: <command>transactional-update up</command>
	Install a package: <command>transactional-update pkg in <replaceable>PACKAGE_NAME</replaceable></command>
	Remove a package: <command>transactional-update pkg rm <replaceable>PACKAGE_NAME</replaceable></command>
	To revert the last snapshot, that is the last set of changes to the root file system, make sure your system is booted into the next to last snapshot and run: <command>transactional-update rollback</command>
	Optionally, add a snapshot ID to the end of the command to rollback to a specific ID.
	When using this system role, by default, the system will perform a daily update and reboot between 03:30 am and 05:00 am. Both of these actions are systemd-based and if necessary can be disabled using <command>systemctl</command>:
	systemctl disable --now transactional-update.timer rebootmgr.service	systemctl disable NetworkManager.service
	For more information about transactional updates, see the openSUSE Kubic blog posts <link xlink:href="https://kubic.opensuse.org/blog/2018-04-04-transactionalupdates/"/> and <link xlink:href="https://kubic.opensuse.org/blog/2018-04-20-transactionalupdates2/"/>.
