This mirrors a nearly identical change made to apt_repository.py.
Also removes the use of apt-get --force-yes as it can be dangerous
and should not be necessary (apt_repository.py does not use it).
Repeating the explanation from the apt_respository change below:
Since use_unsafe_shell is suspicious from a security point
of view (or it wouldn't be unsafe), the less we have, the less
code we have to thoroughly inspect for a security audit.
In this case, the '&&' can be replaced by doing 2 calls to run_command.
Running async_status in an "until: result.finished" loop will mask a module failure (eg, traceback) with a
template failure, because the fail dict doesn't include "finished" (eg, you'll see "ERROR! The conditional check 'bogus_out.finished' failed. The error was: ERROR! error while evaluating conditional: bogus_out.finished ({% if bogus_out.finished %} True {% else %} False {% endif %}"). Because the failure dict still includes "failed: true",
this change has no effect on stoppage/failure reporting, it just prevents the common usage pattern from masking the underlying error message.
Since our validation does conversion as well as validation, I'm not sure
this is entirely correct. May need to take a look at our conversion
code and re-examine to be sure we're doing it right.
I like to use ~/somepath instead of absolute paths because
that's more shareable. Without expansion, the path wasn't
considered a file, and the resulting cloud-config user_data
contained a string for the file path instead of the file context.
So, expand it.
restart_containers(containers.running) may try to restart containers
that are deleted when looping through get_differing_containers()
fix this by refreshing list after first loop
The ulimit will be specified as a list and separated by colons. The
hard limit is optional, in which case it is equal to the soft limit.
The ulimits are compared to the ulimits of the container and added
or adjusted accordingly on by a reload.
The module ensures that ulimits are available in the capabilities
iff ulimits is passes as a parameter.
