When hoisting deploy flags from the option dict, we want the default values to take effect *only if* the option wasn't specified in the dict. Instead, because we initialized the return value with the default flags, the option set couldn't override a flag which was part of the defaults (IOW, a flag that's on by default couldn't be turned off through the options dict). Came upon this issue by trying to use the older `Deploy()` and `Rebase()` D-Bus APIs which pass default values like `ALLOW_DOWNGRADE`, but the option dict specifies `allow-downgrade=false`. (We could say, "you should use the newer `UpdateDeployment()` API", but the cat is mostly out of the bag at this point on options that get shoved into the dict and take effect on both APIs). |

rpm-ostree: A true hybrid image/package system
rpm-ostree combines libostree (an image system), with libdnf (a package system), bringing many of the benefits of both together.

Features:
- Transactional, background image-based (versioned/checksummed) upgrades
- OS rollback without affecting user data (
/usrbut not/etc,/var) via libostree - Client-side package layering (and overrides)
- Easily make your own:

Projects using rpm-ostree
Project Atomic is an umbrella project for delivering upstream container technologies and combined with a minimized, atomically upgradable host system to Fedora, Red Hat Enterprise Linux, and CentOS.
rpm-ostree is the underlying technology for host updates. The headlining project is "Atomic Host", which is a server variant oriented towards running Linux containers using e.g. Kubernetes. However, there is now also a Workstation variant, showing the full generality of the rpm-ostree model.
