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

The Fedora Project is looking for solutions to an interesting
problem with its image-based editions and spins, such as the Atomic Desktops
or CoreOS, that are
created with rpm-ostree or bootc. If a package that
is part of a image-based version has a user or group created
dynamically on installation, and it owns files installed on the
system, 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 with
updates is generated, and therefore files may have the wrong
ownership. This can have side-effects ranging from mildly inconvenient to
serious. No solutions have been adopted just yet, but there are a few
ideas on how to deal with the problem.
