# Run-ShopfloorSetup.ps1 - Main dispatcher for shopfloor PC type setup.

#   1. PreInstall apps (Oracle, VC++, OpenText, UDC) -- from local bundle
#   2. Type-specific scripts (eDNC, ACLs, CMM share apps, etc.)
#   3. Deferred baseline (desktop org, taskbar pins)
#   4. Copy desktop tools (sync_intune, Configure-PC, Set-MachineNumber)
#   5. Run enrollment (PPKG install + wait for completion)
#   6. Register sync_intune as @logon scheduled task
#   7. Reboot -- PPKG file operations complete, sync_intune fires on next logon
#
# Called by the unattend FirstLogonCommands as SupportUser (admin).

# Wired NIC state handling moved to sync_intune (Monitor-IntuneProgress.ps1).
# Previously this script prompted the tech to unplug the PXE cable and
# then re-enabled wired adapters interactively - that blocked the whole
# imaging chain on human keypress. The new flow leaves the wired state
# exactly as Order 5 (migrate-to-wifi.ps1) left it:
#   - Tower (no WiFi): wired stays enabled, Run-ShopfloorSetup runs on wired.
#   - Laptop (WiFi): wired disabled, Run-ShopfloorSetup runs on WiFi.
# Sync_intune re-enables wired at the start of its monitor loop, by which
# time the tech has had ample wall-clock time to physically unplug PXE
# and re-cable into production without blocking the chain on a keypress.
