The Fedora linux_logo package compiles in all available logos, but not in a fixed order. This means the default logo is arbitrary and probably not appropriate - for example, Source Mage on F22, or Solaris on F23. See this post on the devel list, which explains how the logos are found: https://lists.fedoraproject.org/pipermail/devel/2015-October/215262.html
Thanks for figuring that out, as well as suggesting ways to solve the issue :-) I'll have a look at it.
