The Sway package in Fedora defers most of the dependencies and the config file ownership to the sway-config-* subpackages. This allows us to ship different configuration profiles with different sets of runtime dependencies. This also allows anyone to create a package with their preferred system-wide configuration defaults and use it instead of the default Fedora profiles.

The profiles currently defined in the sway source package are the following:

sway-config-upstream - the upstream configuration. The only permitted modifications to the config file are adjustments for dependencies currently unavailable in Fedora.
sway-config-minimal - minimal configuration with any optional dependencies omitted. Suitable for headless servers, containers and buildroot usage.

The config packages are mutually exclusive, and one of these must always be installed. The one selected by default is sway-config-upstream. At any moment, you can switch the installed configuration with one of the following commands:

dnf swap sway-config sway-config-upstream
dnf swap sway-config sway-config-minimal
# for a third-party configuration profile:
dnf swap sway-config sway-config-custom

The command will replace the default /etc/sway/config file and apply the new set of dependencies. Packages unused by the new profile will be autoremoved.

Custom profile example
