If Run() isn't passed a hostname to set, but we have one that was set
directly or inherited from the source image, use that value.

Maintain the container configuration in multiple formats in the Buildah
object, initializing one based on the other, depending on which format
the source image used for its configuration.
Replace directly manipulated fields in the Buildah object (Annotations,
CreatedBy, OS, Architecture, Maintainer, User, Workdir, Env, Cmd,
Entrypoint, Expose, Labels, and Volumes) with accessor functions which
update both configurations and which read from whichever one we consider
to be authoritative. Drop Args because we weren't using them.

When we have cgo, use fgetpwent() to try to look up user IDs and primary
GIDs in containers. If that fails for any reason (or if we don't have
cgo), fall back to doing what we were doing before (i.e., trying to look
up the information on the host).

Make Run() default to running the command with a PTY if we're being run
with stdout connected to terminal, and provide options to force the

When we run a command in Run(), since it's sharing the host's network
namespace, also have it share the host's DNS settings.

one of its subdirectories.

Default to mounting tmpfs over a container's volume mount points. Add a
RunOption for adding mounts to a run container, and use it as the
default set, adding any volume mounts and others that don't conflict
with them to it before running the container.

Provide RunOptions which can be used to change the runtime to something
other than "runc", and add an option that allows passing in additional
global arguments for the runtime.
