[Patrick Swartz (pswartzclan)]

Summary of the Pull Request

Adds RLCPlus-9 and RLCPlus-10 — Rocky Linux Plus, CIQ's free enterprise Linux offering built on Rocky Linux — to the WSL distribution manifest, for both x86_64 and aarch64. RLCPlus-10 is set as the default version.

PR Checklist
Closes: N/A - new distro addition, not tied to an existing issue
Communication: No prior discussion with core contributors on this specific PR. CIQ Rocky Linux Security Team is a current member of the linux-distros security mailing list (https://oss-security.openwall.org/wiki/mailing-lists/distros), which the WSL distro packaging documentation references as a membership criterion.
Tests: No automated tests apply (manifest-only change); manual validation performed and detailed below. validate-modern.py passes clean against this branch with no errors.
Localization: N/A - no new end-user-facing strings introduced beyond the existing FriendlyName field pattern used by other entries.
Dev docs: N/A - no dev-facing documentation changes needed.
Documentation updated: Not yet filed against MicrosoftDocs/wsl - happy to follow up there if maintainers want a docs PR alongside this one.
Detailed Description of the Pull Request / Additional comments

Both RLCPlus-9 and RLCPlus-10 images are built from CIQ's RLC+ GenericCloud qcow2 releases. The build masks NetworkManager/NetworkManager-wait-online/tmp.mount (per the packaging guidance), and additionally masks cloud-init and its related units, since the GenericCloud source image expects a cloud datasource that doesn't exist under WSL - without masking it, first boot hangs indefinitely waiting for a datasource that never arrives.

Build tooling, overlay configuration, and full documentation are public at https://github.com/ctrliq/rlcplus-wsl-images.

Validation Steps Performed

All four combinations (9/10 x x86_64/aarch64) were built and fully boot-tested on real hardware (x86_64 on a Windows desktop, aarch64 on a Snapdragon X2 Plus machine). For each, verified:

Clean install via wsl --install --from-file
OOBE first-run user creation and passwordless sudo
NetworkManager correctly masked, with WSL's own networking still fully functional
Shortcut icon renders correctly in Windows Terminal
/etc/os-release and uname -a confirm correct distro identity and architecture

validate-modern.py --compare-with-branch origin/master run locally against this branch passes with no errors (only the same category of "discouraged system unit" warnings already present on existing, merged entries like Ubuntu).

• Continuation of the indentation inconsistency: the remainder of the RLCPlus-10 entry and the closing ] are not indented to match the surrounding manifest structure.

• Indentation for the RLCPlus-10 entry is inconsistent starting at the Sha256 field in Amd64Url through the end of the RLCPlus array. While JSON whitespace is ignored, this makes the manifest harder to read/review and breaks the established formatting used by the surrounding entries.
