Thin smoke in exhaust pipe on cold start for about 10 second

Smoke color matters. White - could be mild usual condensation. Blue would be oil burning. Major clouds of thick white smoke with a sweet smell could be internal coolant consumption (highly unlikely). Black would be excessive fuel. It might be that it's normal. Seek local guidance for an opinion.
