Custom "--vbox-share" directories are not auto-mounted

[edmorley]

#258 added support for a new "--vbox-share" parameter.

boot2docker help says:

  --vbox-share=[]: (defaults to 'C:\Users=c/Users' if no shares are specified; use 'disable' to explicitly prevent any shares from being created) List of directories to share during 'up|start|boot' via VirtualBox Guest Additions, with optional labels

Trying this:

$ boot2docker start -v --vbox-share="C:\foo"

Like the issue title says, the created VirtualBox shared folders are not mounted inside the vm. Workaround (as of v1.4.1) from within the vm:

sudo mkdir /c/foo
sudo mount -t vboxsf c/foo /c/foo

[LeftenantZero]

Another workaround: Per this documentation https://github.com/boot2docker/boot2docker under "VirtualBox Guest Additions:"

The first of the following share names that exists (if any) will be automatically mounted at the location specified:

    Users share at /Users
    /Users share at /Users
    c/Users share at /c/Users
    /c/Users share at /c/Users
    c:/Users share at /c/Users

(So boot2docker --vbox-share="c:\mymagicdata=/c/users" will auto mount.) Not very flexible or useful long term, but it works.

Closing this out to de-clutter my GitHub open issues dashboard since I believe this repo is deprecated.
