…v9.4 [v9.4] Fix Ubuntu 24.04 user ID collision
The workspace integration test runs MoveIt Pro inside a bridge-networked container on an ephemeral runner -- no TPM, and no interface the licensing fingerprint will accept, since a container veth is rejected by design. Through 9.4.1 that was fine: the fingerprint hashed eth0's MAC and took the veth's. From 9.4.2 (moveit_pro#21596) it resolves a TPM endorsement key, else a permanent hardware NIC, and fails closed with neither -- so this job would stop activating a license the moment it pulls a 9.4.2 image. v0.9.1 is one commit on top of the pinned v0.9.0, adding only the step that builds a synthetic sysfs tree with a fixed MAC and points MOVEIT_HOST_SYSFS at it. No input signature change. The MAC is fixed so the runner fleet presents one identity rather than each ephemeral runner consuming its own activation. v10.0 already pins v0.9.1; this brings the 9.4 line in line ahead of 9.4.2.

Suggested reviewers: Merge Risk: 🟡 Moderate · up to The PR removes competing TF publishers and corrects planar odometry, but the intended single-parent behavior is not achieved on the published v9.4 runtime because its core lacks support for base_link_name; the lidar chain continues publishing a second ridgeback_base_link parent and the integration test fails. Merge should wait for the compatible core to be pinned or published, or for that dependency to be explicitly accepted; the architecture documentation also needs a minor clarification about map-to-odom fallback ownership.

PickNikRobotics picknik_mujoco_ros MujocoSystem base_link_name v9.4
💡 Result:
In the picknik_mujoco_ros package used by MoveIt Pro (version 9.4), there is no specific hardware parameter named base_link_name for the MujocoSystem plugin [1][2][3]. When configuring a robot for MuJoCo within MoveIt Pro, if the root link of your robot in the URDF is named base_link, the standard practice is to handle the MuJoCo URDF-to-MJCF compilation by defining a separate reference link and adding a floating joint [1][2]. You should define a base_link_reference link and use a floating joint to connect it to the actual base_link [1][2]: This ensures that the MuJoCo compiler correctly nests the robot's bodies in the resulting MJCF [1][2]. Official documentation for configuring the MujocoSystem plugin emphasizes defining parameters such as mujoco_model, mujoco_model_package, and various publish rates (e.g., render_publish_rate, tf_publish_rate, lidar_publish_rate), but it does not utilize a base_link_name parameter [3][4][5].

The v9.4 MujocoSystem does not support this parameter. The lidar fill-in chain can therefore publish base_platform → ridgeback_base_link alongside robot_state_publisher, causing test_base_link_has_single_tf_parent to fail.

What Changed
ridgeback_base_link: the MuJoCoros2_controlhardware now setsodom_publish_tf: falseandbase_link_name: ridgeback_base_link(stopping the lidar fill-in chain from broadcastingbase_platform -> ridgeback_base_link), and fuse'spublish_tfis set tofalseso its estimate stays onodom_filtered.robot_state_publisherowns the edge via the virtual-rail chain, sopublish_odomcan staytruefor Nav2's/odom. Also replaced the silently-ignoredodom_zero_zparam with the realodom_planar, and offset thevirtual_rail_joint_1origin toz = -0.048to match the MJCFbase_platform_rotationanchor.robot_drivers_to_persist_sim.launch.py: the static link is nowodom -> worldinstead ofmj_world -> world, and theOpaqueFunctionthat shut the stack down whenuse_fuse:=truewithpublish_odomenabled was deleted along with its now-unused imports.test_base_link_has_single_tf_parentto the hangar_sim objectives integration test — it waits for the first/tfand/odomsighting, then samples for additional parents and assertsvirtual_rail_link_2is the only one and that/odompose z stays zeroed. UpdatedNAV2_AND_WHOLE_BODY_PLANNING_ARCHITECTURE.mdto match the new TF ownership, bumped themoveit_pro_ciintegration-test workflow to v0.9.1, and added auserdelof the stock Ubuntu 24.04ubuntuuser in the Dockerfile to avoid the UID 1000 collision.Risk Assessment
✅ Low: The change is a well-bounded v9.4 backport of a TF-ownership design already reviewed and merged on main via PR #756, the fix round touched only two lines plus doc prose whose factual claims I verified against v9.4 source, and the two remaining findings are a no-op Dockerfile fallback and an inaccurate doc code quote — neither affects runtime behavior.
Testing
Ran the hangar_sim MuJoCo stack for real in MoveIt Pro containers (v9.4, v9.4+moveit_pro#20258 backport, and main) rather than relying on config inspection: the branch's new
test_base_link_has_single_tf_parentfails with the base-commit configuration (three publishers ofridgeback_base_link) and passes on this branch against the paired v9.4 core, a live TF census confirms 3 parents collapse to 1, robot_state_publisher's base pose now matches MuJoCo physics exactly (48 mm z error eliminated),/odomz is zeroed by the correctedodom_planarparameter, theSolution - Move Forward 2mbase-motion objective still passes, anduse_fuse:=truebring-up no longer aborts. The only gap is the change's documented core dependency: on the published v9.4 imagebase_link_nameis absent from the MuJoCo plugin, sobase_platformremains a second parent and the new test fails there — reported for a merge-ordering decision. fuse'spublish_tf:falsecould not be exercised live because the container's fuse binary aborts on an unrelated ABI mismatch./home/griswald/.no-mistakes/evidence/01M0DVX1N2R1XPSRCY17NWDGZR/tf_ownership_evidence.png)Evidence: TF ownership summary (rendered HTML source of the figure)

.github/workflows/ci.yaml- merge conflict rebasing onto origin/mainsrc/hangar_sim/docs/NAV2_AND_WHOLE_BODY_PLANNING_ARCHITECTURE.md:841- The rewritten TF-ownership doc asserts that beluga_amcl publishes a dynamic map->odom and that the static fallback is suppressed underlocalization:=True("the default"). Neither exists in this config:localization_launch.pystarts onlymap_server(AMCL is commented out at line 148),nav2_params.yaml:1states "amcl is not used", there is nolocalizationlaunch argument, andstatic_tf_map_to_odomis gated solely onnot slamwithslamdefaulting to False (robot_drivers_to_persist_sim.launch.py:130, 276). So map->odom is always the static identity in the shipped config. Same claim repeats at lines 807 and 876, and the rationale comment at robot_drivers_to_persist_sim.launch.py:284 justifies the re-parenting with "AMCL's live map->odom correction" for a node that is never launched. This is the reference doc for exactly the TF-ownership question this change exists to settle, so a reader debugging a future frame conflict will look for a nonexistent publisher.src/hangar_sim/launch/sim/robot_drivers_to_persist_sim.launch.py:290- Re-parenting MoveIt's planning rootworldunderodomalso moves the static environment, not just the robot.ur5e_ridgeback.xacro:38attachesxacro:hangar_urdf parent="world", i.e. the whole building (floorcollision_SM_Floor_376, pillars, walls, the plane) is rigidly underworld, which is now underodom. Concrete trace: launch withslam:=True->static_tf_map_to_odomis skipped (line 276 conditionnot slam) -> slam_toolbox publishes a non-identity correction C on map->odom -> TFmap -> collision_SM_Floor_376becomes C * (world->floor), so the hangar itself translates in the map frame every time localization corrects. The doc claim at NAV2_AND_WHOLE_BODY_PLANNING_ARCHITECTURE.md:841 that the correction "shifts the entire robot subtree ... exactly the REP-105 localization semantics" is therefore only half true: REP-105 puts the robot underodom, not the fixed world model. Second consequence of the same edge: in slam mode nothing publishes map->odom at startup, so the robot AND environment subtree is now a disconnected TF root until slam_toolbox comes up, where previouslyworldwas rooted atmj_worldandworld->mapalways resolved. Not reachable in the shipped default (slam=False, no AMCL, map->odom identity), so this is a follow-up rather than a merge blocker; the durable shape is to keep the fixed environment anchored aboveodom(e.g. undermap/mj_world) and put only the robot chain beneath it.src/hangar_sim/description/ur5e_ridgeback.xacro:85- The -48 mm virtual-rail origin correctly re-aligns robot_state_publisher with the physics, but it also shifts every world-frame geometric relationship that was tuned against the old (wrong) model. Two concrete spots: (a) the raster/surface objectives hardcode world-frame crop ROIs, e.g. raster_path_along_fuselage.xml:62position_xyz="0;12;1.7"withcrop_box_size="5;15;0.2"— the wrist-camera cloud now lands 48 mm lower inworld, which is 48% of that slice's half-thickness, so slice membership shifts even though nothing errors; (b) the SRDF ACM was generated with the base at world z=0, andwrist_2_link,wrist_3_link,wrist_3_pinch_link,vacuum_base,vacuum_base_top,vacuum_suction_cupsare the only robot links with nocollision_SM_Floor_376disable pair, so any reach that previously cleared the floor by under 48 mm now plans as in-collision. The integration suite runs these objectives unskipped, so CI does exercise it — flagging so a failure there is read as this shift rather than a flake.src/hangar_sim/config/fuse/fuse.yaml:95- Withpublish_tf: false, fuse's only remaining output in hangar_sim isodom_filtered, and nothing in this package subscribes to it (the onlyodom_filteredconsumers are inmoveit_pro_kinova_configs/space_satellite_sim). Combined withuse_fusedefaulting to "false" (robot_drivers_to_persist_sim.launch.py:185), the entire fuse node, its config, and the RELIABLE-QoS relay path that exists to feed it are now dead weight in this config. Either wire the estimate somewhere (the yaml comment suggests the virtual-rail joint-state bridge) or drop the fuse node and its config from hangar_sim.Dockerfile:28-userdel -r ubuntureturns exit code 12 ("can't remove home directory or mail spool") when /home/ubuntu or /var/mail/ubuntu is absent, which fails the RUN and breaks the image build. That is reachable on any 24.04-derived base image where theubuntuaccount exists but its home has already been pruned — exactly the images where theid -u ubuntuguard passes. Falling back (userdel -r ubuntu || userdel ubuntu) keeps the UID freed without making a missing home fatal.🔧 Fix: Correct fabricated AMCL doc claims; guard userdel exit code
2 infos still open:
Dockerfile:28- The fix-round fallbackuserdel -r ubuntu || userdel ubuntucannot succeed in the scenario it targets. Perman userdel, exit 12 is specifically "can't remove home directory" while exits 1 and 10 cover "can't update password file" / "can't update group file" — so a 12 implies the passwd/shadow/group entries were already committed and only the home/mail-spool removal failed. Concrete trace: base image hasubuntuwith an unremovable /home/ubuntu (bind mount, immutable file) ->id -u ubuntupasses ->userdel -r ubunturemoves the account, fails on the directory, exits 12 -> fallbackuserdel ubunturuns against a now-nonexistent user, exits 6 -> theRUNfails exactly as before. Every other non-zero exit (1 can't-update-passwd, 8 user-logged-in, 10 can't-update-group) reproduces identically on the second invocation, so no exit code reaches the fallback and succeeds. The fallback reads as a guard but is dead. To actually free UID/GID 1000 without making a failed home removal fatal, tolerate the specific code:userdel -r ubuntu || [ $? -eq 12 ](or|| true, which still fails loudly later atuseradd --uid $USER_UIDif the UID was never freed).src/hangar_sim/docs/NAV2_AND_WHOLE_BODY_PLANNING_ARCHITECTURE.md:797- TheTransform Tree Configurationblock is presented as a verbatim quote ofrobot_drivers_to_persist_sim.launch.py:256-272, but it does not match the file and the line range is stale (the actual node definitions span lines 260-297). Most materially, the quotedstatic_tf_map_to_odomat line 808-812 omitscondition=IfCondition(PythonExpression(["not ", slam]))— the single line that decides whether the static fallback is published at all, which is the exact subject of the paragraph two sections below (line 841) that the fix round just rewrote. It also omitsname=andoutput=on all three nodes. Separately, the comment this change introduced at line 807 ("only used when neither SLAM nor AMCL is publishing it") is the last surviving AMCL reference in the doc after the fix round corrected lines 841 and 878; on v9.4 nothing can put AMCL in that position, so the accurate wording is "only used when SLAM is not publishing it". A reader who trusts the block as source will conclude the fallback is unconditional. Fix: correct the line range to 260-297, add thecondition=argument to the quotedstatic_tf_map_to_odom, and drop "nor AMCL" from the comment.src/hangar_sim/description/picknik_ur_mujoco_ros2_control.xacro:41- On the currently published MoveIt Pro v9.4 image (picknikciuser/moveit-studio:v9.4-jazzy-amd64-cuda13.2-cudnn9), the branch's new testtest_base_link_has_single_tf_parentFAILS:saw parents: ['base_platform', 'virtual_rail_link_2'].

The same test PASSES on the paired backport image. This matches the PR's own Dependency section, but it means thehangar_simintegration-test job will stay red until moveit_pro#20258 is backported to v9.4 and the v9.4 images are republished (or until CI is dispatched with that image_ref).
