This fixes a potential races where fuse get's unmouted to late in the shutdown process, i.e., at a time where network was down and it could not talk to any MDS or monitor anymore. We could fix it the same way we did once with the kernel based mount, i.e., adding _netdev, but doing so would require to switch over from "ceph-fuse" to "mount.fuse.ceph" which has better compatibility with the common mount tool API. As that helper exists we can reuse the newer systemd_netmount ephemeral unit generator, only some options differ in name between fuse and kernel variant. So besides solving a potential issue we get a more unified handling of those two cases. Signed-off-by: Thomas Lamprecht <t.lamprecht@proxmox.com>
