I know I could download and unpack the tar.gz file into a directory but I would need to know the version number every time as part of a bash script - thus would be very helpful to be able to run the setup script to install into /opt where I keep my tools

Currently I do not believe the install script offers an option to set the install destination folder. Could you open a suggestion (or even a PR) at https://github.com/pulumi/get.pulumi.com?

Thanks Luke for your suggestion and I opened an issue there: https://github.com/pulumi/get.pulumi.com/issues/47

Great - thanks!

Thanks Luke. Look forward to a fix. About when could it be expected - just curious.

Not immediately clear - if you wanted to share a PR that would help 🙂.
