Does anyone what kernel config enables the uswsusp kernel interface at /dev/snapshot? I tried creating the node in /dev but s2disk rejects the node despite the fact that I issued the exact same command that a patch used to create it before it was taken care of by udev. I must be missing a kernel config to enable this interface but I can't find it anywhere in menuconfig.

This comes from kernel/power/user.c, which is built if you have CONFIG_HIBERNATION enabled.

Whoops! I was searching for CONFIG_HIBERNATE in menuconfig, not CONFIG_HIBERNATION. Thank you!

FYI: Certain grsecurity features are incompatible with hibernation. I found this out after searching for the correct CONFIG_ option.
