Looks OK to me

[smithfarm]

Testing manually in Xenial docker container without sudo package:

$ bash run-make-check.sh 
Checking hostname sanity... OK
Please install sudo and re-run. This script assumes it is running
as a normal user with the ability to run commands as root via sudo.

(Running as root, same thing happens.)

After installing sudo, but not configuring it:

$ bash run-make-check.sh 
Checking hostname sanity... OK
[sudo] password for smithfarm:

As root:

# bash run-make-check.sh
For best results, run this script as a normal user configured
with the ability to run commands as root via sudo.
Checking hostname sanity... OK
[execution continues]

After configuring sudo, execution proceeds as usual.

Next test - CentOS 7.3

Tested manually in CentOS 7.2.1511 docker container:

As normal user in minimal environment:

$ bash run-make-check.sh
Checking hostname sanity... OK
Please install bc and re-run.

As root, same behavior.

After installing bc, behavior is the same as for Xenial, above. It complains about sudo, etc.
