Run now takes a context as well as a statebag. We'll assign the context
to the blank identifier to prevent namespace collisions. We'll let the
step authors opt-in to using the context.
`find . -iname "step_*.go" -exec gsed -i'' 's/func \(.*\)Run(/func \1Run(_ context.Context, /' {} \;`
New config option:
reassign_mac (boolean) - If this is "false" the MAC address of the first
NIC will reused when imported else a new MAC address will be generated by
Parallels. Defaults to "false".
