to the user policy.

Launch is slated for M-64

skau@ - is this blocking remove 20 printers for user settings?

No

ok. In that case, I'll update this bug to reflect that (not blocking "Remove 20 Printers for user settings" -- Issue 755560)

skau@ - assuming this is blocking remove 20 printers for device settings (https://bugs.chromium.org/p/chromium/issues/detail?id=807068#c1)?

This is the bug tracking device settings work

I ended up writing a design doc
go/external-data-for-device-policy

Hey sean... link's not working.

The link should work now.
