[CRIU] Dumping a FUSE mount

Hey everyone,

I want to checkpoint a container that has a mount backed by a FUSE
filesystem. Trying this naively doesn't work:

Error (mount.c:595): FS mnt ./app/available_modules dev 0x118 root /
unsupported id 298

There's a page on the wiki promising instructions, but it's blank:
http://criu.org/FUSE

I don't want to checkpoint the actual FUSE process, it runs externally to
the container, and the directory is mounted readonly. Any suggestions?
