cat << EOF > _SETUP_OK
Tachi(v3) was setup here on $(date).

The existence of this file stops Tachi from running a setup again.
There's nothing harmful about this -- you can setup as much as you want!
We just don't want to necessarily setup *each* time we boot Tachi.

To setup again (in case you think something has gone wrong)
run 'just setup'.
