++	  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
++	default n
++	help
++	  This enables generic device remapping.
++
++config	VSERVER_PROC_SECURE
++	bool	"Enable Proc Security"
++	depends on PROC_FS
++	default y
++	help
++	  This configures ProcFS security to initially hide
++	  non-process entries for all contexts except the main and
++	  spectator context (i.e. for all guests), which is a secure
++	  default.
++
++	  (note: on 1.2x the entries were visible by default)
++
++choice
++	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
++	bool	"Disabled"
++	help
++	  do not store per-context information in inodes.
++
++config	TAGGING_UID16
++	bool	"UID16/GID32"
++	help
++	  reduces UID to 16 bit, but leaves GID at 32 bit.
++
++config	TAGGING_GID16
++	bool	"UID32/GID16"
++	help
++	  reduces GID to 16 bit, but leaves UID at 32 bit.
++
++config	TAGGING_ID24
++	bool	"UID24/GID24"
++	help
++	  uses the upper 8bit from UID and GID for XID tagging
++	  which leaves 24bit for UID/GID each, which should be
++	  more than sufficient for normal use.
++
++config	TAGGING_INTERN
++	bool	"UID32/GID32"
++	help
++	  this uses otherwise reserved inode fields in the on

++	  (will require patched clients too)
++
++config	VSERVER_PRIVACY
++	bool	"Honor Privacy Aspects of Guests"
++	default n
++	help

++	  This setting will optimize certain data structures
++	  and memory allocations according to the expected
++	  maximum.
++
++	  note: this is not a strict upper limit.
++
++config	VSERVER_WARN
++	bool	"VServer Warnings"
++	default y
++	help
++	  This enables various runtime warnings, which will
++	  notify about potential manipulation attempts or

++	  be a good idea to have that enabled.
++
++config	VSERVER_WARN_DEVPTS
++	bool	"VServer DevPTS Warnings"

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

++
++config	VSERVER_HISTORY

++
++config	VSERVER_AUTO_SINGLE
++	bool	"Automatic Single IP Special Casing"
++	depends on EXPERIMENTAL

++	  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

++
++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

++	  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
++	default n
++	help
++	  This enables generic device remapping.
++
++config	VSERVER_PROC_SECURE

++	default y
++	help
++	  This configures ProcFS security to initially hide
++	  non-process entries for all contexts except the main and

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

++	bool	"Disabled"

++	  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
++	default n
++	help
++	  This enables generic device remapping.
++
++config	VSERVER_PROC_SECURE
++	bool	"Enable Proc Security"
++	depends on PROC_FS
++	default y
++	help
++	  This configures ProcFS security to initially hide
++	  non-process entries for all contexts except the main and
++	  spectator context (i.e. for all guests), which is a secure
++	  default.
++
++	  (note: on 1.2x the entries were visible by default)

++	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
++	bool	"Disabled"
++	help
++	  do not store per-context information in inodes.
++
++config	TAGGING_UID16

++	bool	"UID24/GID24"
++	help
++	  uses the upper 8bit from UID and GID for XID tagging

++
++config	TAGGING_INTERN

++
++config	VSERVER_PRIVACY
++	bool	"Honor Privacy Aspects of Guests"

++	  This setting will optimize certain data structures
++	  and memory allocations according to the expected
++	  maximum.
++
++	  note: this is not a strict upper limit.
++
++config	VSERVER_WARN
++	bool	"VServer Warnings"
++	default y
++	help
++	  This enables various runtime warnings, which will
++	  notify about potential manipulation attempts or

++	  be a good idea to have that enabled.
++
++config	VSERVER_WARN_DEVPTS
++	bool	"VServer DevPTS Warnings"

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

++
++config	VSERVER_HISTORY
