Hello Clint, or anyone else affected,
Accepted curtin into trusty-proposed. The package will build now and be
available at
http://launchpad.net/ubuntu/+source/curtin/0.1.0~bzr195-0ubuntu1~14.04.1
in a few hours, and then in the -proposed repository.
Please help us by testing this new package. See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to
enable and use -proposed. Your feedback will aid us getting this update
out to other Ubuntu users.
If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, and change the tag
from verification-needed to verification-done. If it does not fix the
bug for you, please add a comment stating that, and change the tag to
verification-failed. In either case, details of your testing will help

Bug description:
With trusty, /bin/ping relies on having extended attributes and kernel
capabilities to gain the cap_net_raw+p capability. This allows
removing the suid bit.
However, the tarball cloud images do not preserve the extended
attributes, and thus /bin/ping does not work on a system derived from
them.
Summary of problem per package:
* lxc: ubuntu cloud template needs to extract
* download template needs to extract with xattr flags
* server side download creation tools need xattr flags
* [unconfirmed] tarball caches need creation and extraction with xattr flags
* tar: need the '--xattr' and '--acl' flags backported
* maas: uec2roottgz needs to use xattr/acl flags
* curtin: extraction needs to use xattr/acl flags.
* cloud-image-build: needs to create -root.tar.gz with xattr/acl flags
Related Bugs:
* bug 1382632: horizon insecure key file permissions
* bug 1386237: tar strange behavior with --acl and xattr
* bug 1313550: ping broken (xattrs lost in tar extraction)
