If you upgrade from https://dl.fedoraproject.org/pub/alt/stage/22_TC3/ to a later tree, many uids will change, and this will break e.g. ssh.
See: https://git.fedorahosted.org/cgit/fedora-atomic.git/commit/?h=f22&id=3a84472f45532e1cac339ec0cd4f212711f9b9db A script may be provided for upgrades for F21 -> F22 that will help with this. For Fedora 22 updates, please reinstall from media in the TC4 directory: Installer: https://dl.fedoraproject.org/pub/alt/stage/22_TC4/Cloud_Atomic/x86_64/ Cloud images: https://dl.fedoraproject.org/pub/alt/stage/22_TC4/Cloud_Images/x86_64/Images/ or later.
