Thanks Andre, this is a solid cleanup. Testing each runbook step against current main and writing down why the rest didn't make it ("Not adopted from the runbook, and why") made this a quick review. The TMPDIR root cause and the opt-in model overrides look good to me.
One thing I'd like fixed before I approve: the setgid repair can keep openclaw-start from starting at all. Details and a small fix are inline on openclaw-start.sh:31.
A few smaller things:
openclaw-start.sh:116: +1 to CodeRabbit's outside-diff note, which is still open. Ifconfig setfails after onboarding (the EDR exit 137 the README already warns about, for example), the next start finds the config and quietly runs with maxTokens 4096 and reasoning off. That's the failure this PR fixes. Deleting the config and its.bakbeforeexit 1would make the retry onboard again.README.md:102still says everysmoke-test.shcheck passes on the GitHub runners (podman 4.9.3, amd64 and arm64). The new checks only ran on amd64 with podman 5.8.7, so I'd either scope that sentence or re-run there.- The
setgid-homecheck can pass on a mode OpenClaw would reject (inline onsmoke-test.sh:299). - Not for this PR: the TMPDIR problem isn't specific to OpenClaw. The default policy grants
/tmpbut not/var/tmp(crates/openshell-policy/src/lib.rs:986), so any workload using SQLite will hit it. Probably worth an issue to fix it in the default policy or the supervisor's default env.
Two things I checked that turned out fine: the pod uses fsGroupChangePolicy: OnRootMismatch, so kubelet won't put setgid or group bits back on restart, and OpenClaw resolves .openclaw-worker from HOME, so the hardcoded path is right.
Leaving this as a comment for now. Happy to approve once the find change is in.

This find runs under set -e on every openclaw-start call, and OpenClaw's default agent workspace is ~/.openclaw/workspace, so it also walks everything the agent writes there. Two ways that goes wrong:
- a directory it can't read (the agent leaves one at mode 000, say), or
- a directory removed mid-walk, e.g.
sandbox exec -- openclaw-start agent execstarting while a TUI turn is running.
Either one makes find exit 1, so the script stops before the chmod 0700 and the exec, and it fails the same way on every start until someone fixes the directory by hand. I reproduced both with this exact expression: a mode-000 dir gives rc=1 and leaves the root at 755, and with directories churning during the walk it failed 24 times out of 30.
I'd make the repair best effort and add -ignore_readdir_race:
if ! find "${dir}" -xdev -ignore_readdir_race -type d -perm -2000 -user "$(id -u)" -exec chmod g-s {} +; then
echo "openclaw-start: warning: could not clear setgid everywhere under ${dir}" >&2
fiI wouldn't prune the workspace to speed this up, because OpenClaw keeps some private dirs in there (.openclaw-cli-images, for one). If startup time on big workspaces ever matters, a marker under /tmp so the repair runs once per container would be cheap. With OnRootMismatch, kubelet won't set the bit again anyway.

Good catch, fixed in f76ea5f with your version: find now runs with -ignore_readdir_race, and a failure only prints a warning, so the root chmod 0700 and the exec always happen. I left the workspace unpruned for the reason you gave. Verified:
setgid-homenow puts a mode-000 directory in~/.openclaw/workspacebefore the restart. On the previous build it fails withRESTART_FAILED find: '/sandbox/.openclaw/workspace/locked': Permission denied, and it passes now.- Your churn case: 30 starts with directories being created and removed under the workspace, 0 failures (previous build: same failure you saw).

Small one: mkdir -p creates this stale agent dir as 2755, so after the repair it's 0755. The check only looks for leftover setgid, so it passes on a mode OpenClaw's exact-0700 check would reject. Creating it the way OpenClaw leaves it (2700) and asserting 700 afterwards would test what the README promises:
mkdir -p /sandbox/.openclaw/agents/main/agent
chmod 2700 /sandbox/.openclaw/agents/main/agent
# ...after openclaw-start:
agent_mode=$(stat -c %a /sandbox/.openclaw/agents/main/agent)
if [[ "$agent_mode" != 700 ]]; then echo "AGENT_MODE=$agent_mode"; exit 1; fiThere was a problem hiding this comment.
Done in f76ea5f: the stale agent dir is created at 2700, and the check asserts ~/.openclaw, ~/.openclaw-worker and agents/main/agent are all 700 afterwards.
…oxes Clear inherited setgid on OpenClaw state dirs, set TMPDIR=/tmp so SQLite avoids /var/tmp under Landlock, and add opt-in MODEL_MAX_TOKENS, MODEL_CONTEXT_WINDOW and MODEL_REASONING onboarding overrides. Signed-off-by: Andre Lustosa <alustosa@redhat.com>

Summary
An internal user ran
odh-openshell-sandbox-openclawon OpenShift and wrote a runbook with a derivative image and a custom startup wrapper to get it working. They were on gateway 0.0.111, so some of the failures came from that old release. This PR takes the parts that are real on current midstream main and fixes them in the image itself, and leaves out the rest. I reproduced each failure on the current image before fixing it.Related Issue
Related to RHAISTRAT-1845.
Changes
openclaw-startcreates~/.openclawand~/.openclaw-workeras 0700 and clears the setgid bit on every directory under them, on every start. This also repairs sandboxes that already have bad directories.profile.shsetTMPDIR=/tmp.openclaw-startaccepts optionalMODEL_MAX_TOKENS,MODEL_CONTEXT_WINDOWandMODEL_REASONING. They are validated before onboarding and applied to the onboarded model entry once, at first run, like the otherMODEL_*variables.smoke-test.shaddssetgid-home,model-overridesandtmpdirchecks, andlogin-shellnow checksTMPDIR. All four fail on the current image.Adapted from the runbook, and why
chmod g-son the agent directory and its parents, thenchmod 0700fsGroup, so kubelet makes the/sandboxvolume setgid and new directories inherit the bit. OpenClaw requires an existing private secret directory to be exactly 0700, soagents/main/agentfails withinsecure permissions 2700.mkdirand uses~/.openclaw-workertoo. It leaves/sandboxitself alone, since that volume and its group inheritance belong to OpenShell.ENV TMPDIR=/tmp SQLITE_TMPDIR=/tmp/var/tmpbefore/tmpand only checks it withaccess(). Landlock does not blockaccess(), so SQLite picks/var/tmp, which the sandbox policy does not grant, and opening the database fails (fts5: error creating shadow table ...: unable to open database file).TMPDIR=/tmponly. SQLite readsSQLITE_TMPDIRfirst andTMPDIRsecond, so one variable covers SQLite and Node. It is also set inprofile.shfor login shells.openclaw config setreplacing the whole model list withreasoning: trueandmaxTokens: 32768maxTokens: 4096andreasoning: false, with no flag to change either. A reasoning model spends the allowance thinking and OpenClaw reportsAgent couldn't generate a response(stopReason=length payloads=0).MODEL_IDsays. Nothing is hardcoded for one model. The default stays at OpenClaw's 4096 because the right limit depends on the server.Not adopted from the runbook, and why
iprouteandutil-linux-corefor/usr/sbin/ipand/usr/bin/nsenteropenclaw-agent-schema-*.mjsTMPDIRbug: the failed temp-file open leaves a half-built database. WithTMPDIR=/tmp, OpenClaw builds its own schema. The workaround is also fragile, because it hardcodes schema version 24 and parses minified code./dev/null/dev/nullread-write.openshell policy update --add-endpointafter every sandbox createpolicy:_provider_<name>), with no extra rule.npm install.openclaw-openshell-startwrapperopenclaw-start, so the documented-- openclaw-startcommand works as it is.Testing
build-local.sh openclaw(hermetic, linux/amd64, rootless podman 5.8.7): the build succeeds and all 16smoke-test.shchecks pass. The four new or extended checks fail on an image built from current main.shellcheckonopenclaw-start.sh,profile.shandsmoke-test.sh, andmarkdownlint-cli2on the README, pass.fsGroup, so/sandboxis 2777 with setgid, and the sandbox runs as UID 10001 with no passwd entry. Steps: lint and import the example profile, create the provider, create the sandbox, run a headlessagent execturn, then drive an interactive TUI turn."/sandbox/.openclaw/agents/main/agent" has insecure permissions 2700, the headless turn fails with the FTS5unable to open database fileerror, and setgid directories are left under~/.openclaw.maxTokensfailure was reproduced with the stub (max_tokens: 4096,stopReason=length), and fixed withMODEL_MAX_TOKENS=16384.Checklist
