udiskie will be used to automatically mount drives. It may be installed with.

# xpbs-install -Sy udiskie

udiskie needs to be started in Wayfire. This can be obtained by editing .config/wayfire.ini.

[autostart]
automount = udiskie -As

Furthermore, udiskie needs permission to mount drives, this permission can be given by creating /etc/polkit-1/rules.d/00-mounting.rules and inserting:

polkit.addRule(function(action, subject)
{
	if (action.id.startsWith("org.freedesktop.udisks2.") && subject.isInGroup("storage"))
		return polkit.Result.YES;
});

or

# cp {config-files-repo}/polkit/00-mounting.rules /etc/polkit-1/rules.d/
