Otherwise, OK for me.

Note that this has the potential to break upgrades of existing systems,
since the range allocated to generated users has changed, and thus may
no longer match the UIDs/GIDs of files created on the device.

But we never ever made the promise that this would work anyway, so I am
totally OK with changing this range.
