import aws_security_group is importing aws_security_group_rules also

[John Parfitt]

is there anyway i can stop this behavior? my sg rules are defined within the aws_security_group themselves, not individually. i do not want my tfstate to have aws_security_group_rules as well. it is redundant. i currently have about 20 sgs that i need to import, to rectify my tfstate with my actual infrastructure. i'm currently running the import and then going into tfstate and manually removing all aws_security_group_rule sections.

Terraform treats an import of the aws_security_group resource as a complex import, because it has dependencies on other resources - in this case, aws_security_group_rule. Where no dependencies were found, it would be a simple import.

Hacking the statefile manually isn't the best thing to do; if you're using a modern version of Terraform, then you can make use of `terraform state rm` as documented at https://www.terraform.io/docs/commands/state/rm.html to remove individual resources from the state file in a safer way.

Whilst hacking the statefile manually may work, it's a little less safe than doing it through Terraform.

Yeah if you have terraform import then you have `terraform state list` and `terraform state rm`. not sure if terraform will repopulate the rules within the security group resource, but seems like a terraform apply would fix that. But don't touch the tfstate file if you don't have to.
