module Systems
# The base class for a "system." A system represents an installed
# operating system on a given box. There are some portions of
# Vagrant which are fairly OS-specific (such as mounting shared
# folders) and while the number is few, this abstraction allows
# more obscure operating systems to be installed without having
# to directly modify Vagrant internals.
#
# Subclasses of the system base class are expected to implement
# all the methods. These methods are described in the comments
# above their definition.
#
# **This is by no means a complete specification. The methods
# required by systems can and will change at any time. Any
# changes will be noted on release notes.**

# Initializes the system. Any subclasses MUST make sure this
# method is called on the parent. Therefore, if a subclass overrides
# `initialize`, then you must call `super`.

end
# This method is automatically called when the system is available (when
# Vagrant can successfully SSH into the machine) to give the system a chance
# to determine the distro and return a distro-specific system.
#
# **Warning:** If a return value which subclasses from {Base} is
# returned, Vagrant will use it as the new system instance for the
# class.

# Halt the machine. This method should gracefully shut down the
# operating system. This method will cause `vagrant halt` and associated
# commands to _block_, meaning that if the machine doesn't halt
# in a reasonable amount of time, this method should just return.
#
# If when this method returns, the machine's state isn't "powered_off,"
# Vagrant will proceed to forcefully shut the machine down.

# Mounts a shared folder. This method is called by the shared
# folder action with an open SSH session (passed in as `ssh`).
# This method should create, mount, and properly set permissions
# on the shared folder. This method should also properly
# adhere to any configuration values such as `shared_folder_uid`
# on `config.vm`.
