# Lazy-unmount gvfsd-fuse filesystems before suspend/hibernate to prevent the
# kernel's process freeze from timing out. FUSE daemons (like gvfsd-fuse from
# Nautilus) can block in uninterruptible sleep during freeze, causing suspend
# to silently fail. After wake, restart gvfs so the FUSE mount is restored.
