Looking into this a bit closer, it looks like systemd installs a symlink:
/usr/lib/systemd/system/sysinit.target.wants/sys-fs-fuse-connections.mount
-> ../sys-fs-fuse-connections.mount
I think removing this symlink would prevent /sys/fs/fuse/connections
from being mounted and the fuse module from being loaded
unconditionally on boot.
As well, udev installs a couple of relevant rules (50-default.rules,
99-systemd.rules):
KERNEL=="fuse", MODE="0666", OPTIONS+="static_node=fuse"
# Asynchronously mount file systems implemented by these modules as
soon as they are loaded.
SUBSYSTEM=="module", KERNEL=="fuse", TAG+="systemd",
ENV{SYSTEMD_WANTS}+="sys-fs-fuse-connections.mount"
I think these rules should take care of providing a static /dev/fuse
node to allow module auto-loading, and should cause
/sys/fs/fuse/connections to be mounted on-demand.
