As mentioned here
Fedora OS/Linux seems to be (partially) the upstream of the mobile operation system SailfishOS.
SailfishOS (SFOSX) is systemd/rpm based and has his roots in MeeGo (Nokia).
Nice to see the overlap and I thought to mentioned it here. I can imagine that the one or other find it interesting. Not sure if a collaboration could also be an interesting endevour?
