GE-Enforce mounts the SFLD share on W: and holds it for the whole enforce
cycle, passing W:\<pctype> as -InstallerRoot to Install-FromManifest. Two
scripts that run inside that cycle, as SYSTEM in the same drive namespace,
mapped W: for their own use and deleted it on exit:
Restore-UDCData.ps1 manifest PS1 entry, mounts the UDC backup share
Update-MachineNumber.ps1 "Apply Machine Number" task, same backup share
Once W: is gone, the next manifest entry's Join-Path resolves against a dead
drive qualifier. In Windows PowerShell 5.1 that emits nothing rather than
throwing, so the null lands in Test-Path -LiteralPath and the entry dies with
"Cannot bind argument to parameter 'LiteralPath' because it is null".
Observed on a collections bay: the controller-credential entry, which runs
immediately after UDC Data Restore, failed this way while the entry one line
earlier had resolved a W: path successfully one second before.
Restore-UDCData now uses R: and Update-MachineNumber uses N: for the UDC
backup share. Neither letter is referenced anywhere else in the tree; V: was
not an option because Restore-EDncReg and Update-MachineNumber's NTLARS
restore already use it.
The re-mount at GE-Enforce.ps1:239-244 does not cover this. It runs after the
manifest loop and blames idle SMB timeout, but the whole cycle took one
second, so timeout was never the cause.
Bundles drift left uncommitted from prior sessions and the UDC matrix
verify entry added today.
Drift items (all per session-progress.md, completed in earlier sessions
but never staged):
- playbook/check-bios.cmd (deleted, moved to BIOS/check-bios.cmd)
- playbook/migrate-to-wifi.ps1 (made no-op 2026-04-24 after the dnsmasq
no-gateway fix removed the wired-NIC race that motivated it)
- playbook/preinstall/oracle/Install-Oracle11r2.cmd (post-OUI .ora copy
added 2026-04-24)
- playbook/preinstall/oracle/tnsnames.ora (live tnsnames, 469 KB,
deployed alongside the wrapper 2026-04-24)
- playbook/pxe_server_setup.yml (dnsmasq dhcp-option=3,6 commented,
Oracle .ora deploy task added 2026-04-24)
- playbook/shopfloor-setup/BIOS/{check-bios.cmd, models.txt} (BIOS
detection refinements)
- playbook/shopfloor-setup/Shopfloor/Force-Lockdown.bat
- playbook/shopfloor-setup/Shopfloor/Monitor-IntuneProgress.ps1
- playbook/shopfloor-setup/Shopfloor/SetShopfloorAutoLogon.bat (new)
- playbook/shopfloor-setup/Shopfloor/09-Install-PrinterInstallerMap.ps1
(new, places PrinterInstallerMap.exe + Public Desktop shortcut at
imaging time; manifest entry self-heals on tamper)
- playbook/shopfloor-setup/Shopfloor/lib/Show-IntuneDeviceQR.ps1 (new,
standalone QR rendering for site that wanted just that piece)
- playbook/shopfloor-setup/gea-shopfloor-collections/{Install-eMxInfo.cmd.template,
Restore-UDCData.ps1} (these were uncommitted in pre-rename Standard/;
git mv didn't catch them because they were untracked at the time)
- docs/shopfloor-machine-imaging-guide.md (operator-facing how-to)
Matrix:
- common.test/matrix.json: add UDC verify entry to gea-shopfloor-collections
row. Surfaces UDC silent-install issue (item H pending) instead of
letting it pass silently.
.gitignore:
- PrinterInstallerMap.exe (142 MB) excluded. Track via LFS or stage on
PXE server only - too big for regular git history. Untouched on disk
so existing local copy still works.
