fs_setup: if cmd is specified, use shell interpretation.
If 'cmd' is provided to a fs_setup entry, then cloud-init was trying
to execute the rendered string as a single name, rather than
splitting the string. The change here will pass the string to
shell for interpretation so that it is split there.
Also fix some documentation errors and warn when fs_opts or overwrite
is provided along with 'cmd'.
doc: document network configuration defaults policy and formats.
Add documentation for cloud-init networking configuration formats, default
behavior, policy and other specific details about how network config is
consumed and utilized.
Fix name of "uri" key in docs for "cc_apt_configure" module
The key is called "uri", not "url". This is what's used throughout the
examples and also what works in practice (verified on Ubuntu 16.10).
This also slightly improves formatting of the key names in the
related documentation.
nova-lxd: read product_name from environment, not platform.
Apparently signals were crossed when this implementation was done.
Cloud-init was reading 'platform' in the environment of pid 1, but
nova-lxd was setting 'product_name'.
The fix is being made here in cloud-init to instead read product_name.
Fix yum repo config where keys contain array values
ConfigObj produces configuration files that are incompatible with yum if
multiple values are listed for a configuration key. Switch to the builtin
configparser, and ConfigParser (Python 2) which correctly handles this
case.
Add additional test case for array values in yum_repos definition
The discard action (tilde character) has been replaced by the
“stop” RainerScript directive. It is considered more intuitive and
offers slightly better performance.
The tilde operator was deprecated in rsyslog 7. Distributions
using rsyslog older than that will need to patch.
