** Description changed:
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

+ SRU curtin
+ ==========
+
+ [Impact]
+
+ As the original bug report description mentions, curtin's extraction
+ needs to use xattr/acl flags.
+
+ [Test Case]
+
+ To reproduce this bug, use curtin extraction without the extended file
+ attributes.
+
+ [Regression Potential]
+
+ TBD
