Hey Testers,
Monday, 2020-07-06 will be SwapOnZRAM Test Day[0]!
This Test Day will focus on SwapOnZRAM[1]. Swap partition is useful,
except when it's slow. Zram is a RAM drive that uses compression.
Create a swap-on-zram during start-up. And no longer use swap
partitions by default.
The zram module creates RAM based block devices named /dev/zram<id>
(<id> = 0, 1, ...). Pages written to these disks are compressed and stored
in memory itself. These disks allow very fast I/O and compression provides
good amounts of memory savings.
It's also pretty easy to join in and contribute, you can submit your
test day results here[2]
As always, the event will be in #fedora-test-day on Freenode IRC.

Hmm... it mentions that Fedora 31 would be ok for the tests, but
the zram-generator package is not available on Fedora 31:
https://dl.fedoraproject.org/pub/fedora/linux/updates/31/Everything/x86_6...
Assuming that CONFIG_ZRAM is enabled on Fedora 31, you should either
backport zram-generator packages to Fedora 31 or update the test day
page accordingly.
Thanks,
Mauro

Hmm... it mentions that Fedora 31 would be ok for the tests, but
the zram-generator package is not available on Fedora 31:
https://dl.fedoraproject.org/pub/fedora/linux/updates/31/Everything/x86_6...
Assuming that CONFIG_ZRAM is enabled on Fedora 31, you should either
backport zram-generator packages to Fedora 31 or update the test day
page accordingly.
The package is fully backwards compatible, so it would be OK to simply
push the latest version to F31. But there isn't enough time to go
through updates-testing. So I think we should ask people to install the package
directly from koji:
sudo dnf install
https://kojipkgs.fedoraproject.org/packages/rust-zram-generator/0.2.0~rc....
-p`/zram-generator-0.2.0~rc.1-1.fc32.`uname -p`.rpm

It is available on F31, I have it installed. When I checked the
version, I found that it's a module, so you wouldn't see it in that
location. You can just dnf install it and it will work.
# rpm -q zram-generator
zram-generator-0.1.2-1.module_f31+6778+c4fd1ff5.x86_64

Igor has now built new packages in koji for fc31, fc32, and fc33. I
expect we'll use those for the test day. Thanks Igor!

# rpm -q zram-generator
zram-generator-0.1.2-1.module_f31+6778+c4fd1ff5.x86_64
My recommendation is to uninstall that one, and install the latest
version in koji, including the new 'zram-generator-defaults' package
if you want it enabled by default. So the main difference: the
permanent/default configuration file is provided by the defaults
package which puts a config in a /usr location, and it can be
overridden by creating a configuration in /etc. To disable it, either
create an empty config in /etc or remove defaults package.
This makes it all more consistent with systemd's conventions, compared
to how it originally was presented.

If anyone else has trouble finding it in koji like I did, note that the
source package is actually "rust-zram-generator":
