- the sysprep.sh script was not executable (flagged by rpmlint)
- Need to explicitly `require 'tmpdir'` in `spec_helper.rb` on openSUSE
Tumbleweed,
otherwise you get tons of failures like:
```
An error occurred while loading ./spec/unit/action/prepare_nfs_settings_spec.rb.
Failure/Error: temp_dir = Dir.mktmpdir("rspec-")
NoMethodError:
undefined method `mktmpdir' for Dir:Class
temp_dir = Dir.mktmpdir("rspec-")
^^^^^^^^^
Did you mean? mkdir
# ./spec/spec_helper.rb:44:in `block in <top (required)>'
# ./spec/spec_helper.rb:41:in `<top (required)>'
# ./spec/unit/action/prepare_nfs_settings_spec.rb:3:in `require'
# ./spec/unit/action/prepare_nfs_settings_spec.rb:3:in `<top (required)>'
```
Move existing tests executed with the help of bats to use rspec directly
combined with tags to filter them out from being executed by default.
This allows for more complex assertions as well as easier debug as the
code supports use of setting 'VAGRANT_SPEC_SKIP_CLEANUP' to prevent the
tests from removing the temporary directory created for home and work
directories.
Extend a number of classes from vagrant-spec to override default
behaviour to allow passing of additional environment variables for
packaging tests, as well as supporting the skip cleanup. Given the use
of after to perform the cleanup, need to vendor the vagrant-spec
acceptance context in order to modify it easily.
