📝 WalkthroughWalkthroughThe PR centralizes registry data-directory resolution, adds root and XDG-based defaults, validates and creates directories, updates startup wiring, changes Zot configuration defaults, and expands tests and documentation. ChangesRegistry storage path
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to The change alters default registry storage resolution and startup configuration handling. At the current head, persisted settings can be replaced, bypass modes may still perform unintended embedded-registry setup, and root-level testing is unreliable, so merge should wait for these issues to be fixed.

Make this test independent of the runner UID.
Line 206 calls ResolveRegistryDataDir(""), which uses os.Geteuid(). When the test runs as root, it ignores XDG_DATA_HOME, creates /var/lib/satellite/registry, and fails the expected-path assertion.
Inject the default-path selector into an internal resolver, or otherwise isolate directory creation in a temporary test path. Keep root and XDG selection coverage in TestDefaultRegistryDataDir.

Default registry path now follows XDG conventions instead of being derived from the config directory: /var/lib/satellite/registry for root, /satellite/registry (or ~/.local/share/...) for non-root users. PR container-registry#260 added the override flag/env var but never implemented these defaults, per container-registry#230.

Preserve configured Zot settings when no registry-data override is set.
InitConfigManager loads persisted zot_config, but BuildZotConfigWithStoragePath rebuilds it from DefaultZotConfigJSON. When no --registry-data-dir or REGISTRY_DATA_DIR value is set, this replaces the configured storage path and other Zot settings. Preserve them unless an override is provided, and add a regression test.

Description
#260 added
--registry-data-dir/REGISTRY_DATA_DIRas an override, but the default path (no flag/env set) still derived from the config directory rather than following XDG/FHS conventions, as #230 asked for.This adds that:
/var/lib/satellite/registry.$XDG_DATA_HOME/satellite/registry, falling back to~/.local/share/satellite/registry.An earlier follow-up (#473) attempted this but was closed after going stale on review.
This stays scoped to just the remaining items from #230.
