bundle 2.29

It's been a long time since I released a new version of this.

Hua provided a patch to specify a directory for bundle to cd into before applying a bundle. This looks like an odd feature to want, but we frequently want to apply a bundle as an action in remctl and pull the files from an AFS directory that's access-restricted. We run bundle under kstart, but we can't cd until after kstart obtains the right tokens. This feature avoids having to have kstart start sh -c or writing another shell script wrapper around the bundle.

You can get the latest version from the bundle distribution page.
