+ string ' Default resume device name'
+ depends on SUSPEND2
+ ---help---
+ You normally need to add a resume2= parameter to your lilo.conf or
+ equivalent. With this option properly set, the kernel has a value
+ to default. No damage will be done if the value is invalid.
+
+ config SUSPEND2_KEEP_IMAGE
+ bool ' Allow Keep Image Mode'
+ depends on SUSPEND2
+ ---help---
+ This option allows you to keep and image and reuse it. It is intended
+ __ONLY__ for use with systems where all filesystems are mounted read-
+ only (kiosks, for example). To use it, compile this option in and boot
+ normally. Set the KEEP_IMAGE flag in /proc/suspend2 and suspend.
+ When you resume, the image will not be removed. You will be unable to turn
+ off swap partitions (assuming you are using the swap writer), but future
+ suspends simply do a power-down. The image can be updated using the
+ kernel command line parameter suspend_act= to turn off the keep image
+ bit. Keep image mode is a little less user friendly on purpose - it
+ should not be used without thought!
