[$] Addressing UID/GID drift in rpm-ostree and bootc

The Fedora Project is looking for solutions to an interestingproblem with its image-based editions and spins, such as the Atomic Desktopsor CoreOS, that arecreated with rpm-ostree or bootc. If a package thatis part of a image-based version has a user or group createddynamically on installation, and it owns files installed on thesystem, the system may be subject to user ID (UID) and group ID (GID) "drift"on updates. This "UID/GID drift" may come about when a new image withupdates is generated, and therefore files may have the wrongownership. This can have side-effects ranging from mildly inconvenient toserious. No solutions have been adopted just yet, but there are a fewideas on how to deal with the problem.
