It seem the nova-api's env does not pass on to its sub process 'sudo'?

[Ethan Lynn (ethanlynn)]

Any update for it？

[fujioka yuuichi (fujioka-yuuichi-d)]

Is this a devstack bug?

"sudo nova-rootwrap" is hardcoded at https://github.com/openstack/nova/blob/279c2b0a015b67c5195ab028eeab15b00a94e5ee/nova/utils.py#L254.

I feel this is a nova bug.
