I am making a live CD based on debian-live, and wanted to include sshfs (for transferring large files over an ssh connection.) However, this means the live CD user must be in the "fuse" group, and I haven't found a way to make that happen automatically. I've tried chroot_local-hooks and chroot_local-includes/usr/share/initramfs-tools/scripts/99something, but to no avail.
