-+	  startup.
-+
-+config	VSERVER_AUTO_SINGLE
-+	bool	"Automatic Single IP Special Casing"
-+	depends on EXPERIMENTAL
-+	default y
-+	help
-+	  This allows network contexts with a single IP to
-+	  automatically remap 0.0.0.0 bindings to that IP,
-+	  avoiding further network checks and improving
-+	  performance.
-+
-+	  (note: such guests do not allow to change the ip
-+	   on the fly and do not show loopback addresses)
-+
-+config	VSERVER_COWBL
-+	bool	"Enable COW Immutable Link Breaking"
-+	default y
-+	help
-+	  This enables the COW (Copy-On-Write) link break code.
-+	  It allows you to treat unified files like normal files
-+	  when writing to them (which will implicitely break the
-+	  link and create a copy of the unified file)
-+
-+config	VSERVER_VTIME
-+	bool	"Enable Virtualized Guest Time"
-+	depends on EXPERIMENTAL
-+	default n
-+	help
-+	  This enables per guest time offsets to allow for
-+	  adjusting the system clock individually per guest.
-+	  this adds some overhead to the time functions and
-+	  therefore should not be enabled without good reason.
-+
-+config	VSERVER_DEVICE
-+	bool	"Enable Guest Device Mapping"
-+	depends on EXPERIMENTAL

-+	  This enables generic device remapping.
-+

-+	bool	"Enable Proc Security"
-+	depends on PROC_FS
-+	default y
-+	help
-+	  This configures ProcFS security to initially hide

-+	  default.
-+
-+	  (note: on 1.2x the entries were visible by default)

-+	prompt	"Persistent Inode Tagging"
-+	default	TAGGING_ID24
-+	help
-+	  This adds persistent context information to filesystems
-+	  mounted with the tagxid option. Tagging is a requirement
-+	  for per-context disk limits and per-context quota.
-+
-+
-+config	TAGGING_NONE

-+
-+config	TAGGING_INTERN
-+	bool	"UID32/GID32"
-+	help

-+
-+config	VSERVER_PRIVACY
-+	bool	"Honor Privacy Aspects of Guests"
-+	default n
-+	help
-+	  When enabled, most context checks will disallow

-+
-+	  note: this is not a strict upper limit.
-+
-+config	VSERVER_WARN
-+	bool	"VServer Warnings"
-+	default y
-+	help
-+	  This enables various runtime warnings, which will

-+
-+config	VSERVER_WARN_DEVPTS
-+	bool	"VServer DevPTS Warnings"
-+	depends on VSERVER_WARN
-+	default y
-+	help
-+	  This enables DevPTS related warnings, issued when a

-+
-+config	VSERVER_DEBUG
-+	bool	"VServer Debugging Code"
-+	default n
-+	help
-+	  Set this to yes if you want to be able to activate
