How to distinguish if a systemd unit is run by apt-get or during boot?

Can one somehow distinguish if,

    a) the daemon was started during boot or,
    b) (re)started by an apt-get install or upgrade?

Can this be distinguished from within the daemon itself?

The use case is here to have script that is run by systemd
'Type=oneshot' only run on boot. Not during apt-get install or upgrades.
