- encapsulated code in functions to make it more readable
- validate presence of used tools/binaries (check if they're in PATH)
- more output
- FIX: make all uname/OSTYPE output to lowercase and check only for that
- refactored method name convert_path -> convertPathOnCygwin
- gave convert_path two arguments to make it more readable (Readability over tight code? I don't know what is required)
- some variable expansion now uses braces
This commit rewrites the Vagrantfile for Packer in a similar manner to
the work done for Nomad (hashicorp/nomad#3175) in order to make
cross-platform development easier. It also adds support for a FreeBSD
base box.
Provisioning scripts are separated out in order that they can be
correctly linted. Each script is prefixed `vagrant`, then the operating
system, then whether or not it expects to be run in a privileged shell.
Finally, dependencies have been bumped - Go 1.6 is switched out for the
latest (1.9.2).
This fixes building `packer` with Go >1.6. From https://golang.org/cmd/link/:
```
-X importpath.name=value
Set the value of the string variable in importpath named name to value.
Note that before Go 1.5 this option took two separate arguments.
Now it takes one argument split on the first = sign.
```
