euca-bundle-vol places filesystem in subdirectory

[Matthew Powell]

euca-bundle-vol should be able to create a bundle from a mounted filesystem using the -v option. However, the image it creates contains the filesystem in a subdirectory, not at the filesystem root:

For example, with my "root" filesystem mounted at /imagebuild/image, I ran the following:

euca-bundle-vol -v /imagebuild/image -p my-rhel-image -d /imagebuild/bundle -e /imagebuild/bundle/var/lib/dhclient --no-inherit

I expected the contents of /imagebuild/image to be the image root, but the image created contained a subdirectory called "image" that contained my files instead.

Knowing that euca-bundle-vol uses rsync, I next tried this:

euca-bundle-vol -v /imagebuild/image/ -p rhel-sshkey -d /imagebuild/bundle -e /imagebuild/bundle/var/lib/dhclient --no-inherit

but got the same result.

Looking at the euca-bundle-vol script, it uses Python's os.path.normpath, which strips the trailing slash before passing the path to rsync, so the directory given for -v will always be created as a subdirectory in the image. See http://bugs.python.org/issue1707768.

Removing the line "volume_path = os.path.normpath(volume_path)" from the euca-bundle-vol script makes my second command (with the trailing slash) work as I expected.

Perhaps euca-bundle-vol should always add a trailing slash before passing the path to rsync, though.

this seems a euca2ools issue.
