QA:Testcase Atomic read only mounts

Description

In an Atomic instance different directories are supposed to be read only mounts. This test verifies the same.

Setup

You should have an Atomic instance running in Cloud/vagrant or in bare metal.

How to test

Be as specific as required for the target audience.

1. Login to the Atomic instances, if cloud/vagrant then ssh into it.
2. Next we will try to create files in different directories.

$ sudo touch /bin/hello.txt
$ sudo touch /sbin/hello.txt
$ sudo touch /usr/hello.txt

Expected Results

The following must be true to consider this a successful test run. Be brief ... but explicit.

1. Step #1 completes without error
2. All 3 touch commands are supposed to fail to create the hello.txt file. Excepted output like

$ sudo touch /bin/hello.txt
touch: cannot touch ‘/bin/hello.txt’: Read-only file system
$ sudo touch /sbin/hello.txt
touch: cannot touch ‘/sbin/hello.txt’: Read-only file system
$ sudo touch /usr/hello.txt
touch: cannot touch ‘/usr/hello.txt’: Read-only file system

1. Each of those commands completes with exit code 1

Optional

Optionally provide hints for exploratory testing.
