== Summary ==

For cloud installs of Fedora, we want to provide advanced file system
features to users in a transparent fashion. Thus, we are changing the
file system for the Cloud Edition to Btrfs so we can leverage its
features and capabilities to improve the quality of experience for
Cloud users.

...
== Detailed Description ==

Fedora Cloud Edition will switch to using Btrfs for its images. The
configuration for the Cloud Edition will match the setup used on the
desktop variants, as this has been very well-tested with production
deployments across multiple Fedora Linux releases now.

This includes the same subvolume layout that is used on the desktop
variants [[Changes/BtrfsByDefault|as introduced in Fedora Linux 33]],
as well as transparent Zstd compression
[[Changes/BtrfsTransparentCompression|as introduced in Fedora Linux
34]].


Wonder why a cloud image would just have a special affinity for a desktop system. Who runs their desktop in the cloud?

And there is a reason why the partition layout of server and desktop differs.  


== Release Notes ==

The default file system on the cloud is now Btrfs, following the
desktop change in Fedora Linux 33. Fedora Server, IoT, and CoreOS are
still specifically excluded.

It wasn't long ago that the plan was to better align cloud and server.
