OK, that test failed:  systemd does *not* stop attempting to mount a
partition after x-systemd.device-timeout has passed.

Here's the line in /etc/fstab:

    /dev/Freeze02/Store2		/Store         ext4	nofail,x-systemd.device-timeout=1m,defaults	0 0

And here's /run/systemd/generator/Store.mount:

    # Automatically generated by systemd-fstab-generator

    [Unit]
    SourcePath=/etc/fstab
    DefaultDependencies=no
    After=local-fs-pre.target
    Conflicts=umount.target
    Before=umount.target

    [Mount]
    What=/dev/Freeze02/Store2
    Where=/Store
    Type=ext4
    FsckPassNo=0
    Options=nofail,x-systemd.device-timeout=1m,defaults
