"more-or-less" ? ;-)

What's the overall idiom for use here, something like:

Against the production DB:
OSSTEST_TASK=ianc@testing-somethingÂ./mg-allocate [-U ...] a-host

./mg-schema-test-database create [_SUFFIX]Âianc@testing-something

Ending up in a state where a-host is allocated in the production db and
idle in this new test db and all other hosts are allocated in the test db
and left to go about their usual business in the production db?

I glanced through this, but TBH I don't think picking through it line by
line will be very productive, I trust you've tested it and its ok...

Ian.
