TWO SCRIPTS, DIFFERENT AUDIENCES
playbook/scripts/preflight.ps1 runs at the bay, called by startnet once the
media is mapped. It checks the four things that come straight out of PESetup's
own behaviour:
secure boot GatherDataSelection fails outright when SecurebootEnabled != 1
disk >= 120GB MinRequiredSpaceWithoutCompression is 128849018880
driver match reimplements GetDriverByModel - family filter, untrimmed
comma-separated substring tokens, first match wins - and checks
the pack is actually on the media
media age media expires 30 days after build; Media.tag's timestamp is the
local proxy
The driver check is the one that earns it. A miss is only a WARNING to PESetup,
so the bay images with no NIC, DNS fails at first boot, and enrollment cannot
reach the CDN - a symptom three steps removed from the cause. Advisory by
design: it reports and pauses on a blocker, the tech decides. Lives on the
enrollment share so it can be fixed without rebuilding boot.wim.
scripts/preflight.py runs on the server before a build day and aggregates
everything already built - driver catalogue lint, unattend lint, per-PCTYPE
media view verify - plus a new advisory firmware-coverage check that lists
catalogued models with no BIOS models.txt entry. That last one is how the
OptiPlex 7020 family sat uncovered: 127 catalogued models, 58 covered today.
First run: driver catalogues clean, all three unattends clean, firmware coverage
advisory only. PREFLIGHT PASSED.
Verified: both scripts parse clean (PowerShell parser / python), startnet parens
balance, every goto resolves, 915 CRLF lines with no bare LF. Deployed -
boot.wim md5 99fd3132, preflight.ps1 on the share.
