fail to mount of virtualbox shared folder from init daemon to systemd

before

first. I wrote on the mount command to /etc/rc.local

   mount -t vboxsf  -o uid=1000,gid=1000,dmode=0755,fmode=0755 Dropbox /home/murase_syuka/Dropbox

but, it is fail when change from init to systemd

now

it is success when run on terminal.
but is not automatic is a manual

after

make the systemd unit for auto mount to vbox shared folder.

reinstall vbox guest addition disk

first, I check to the running of virtualbox service.

    $ systemctl list-units
    ...
    [[1;31mvboxadd-service.service                                       ^[[0m loaded ^[[1;31mfailed failed   ^[[0m LSB: VirtualBox Additions service
    vboxadd.service                                                loaded active exited    LSB: VirtualBox Linux Additions kernel modules
    virtualbox-guest-utils.service                                 loaded active running   LSB: VirtualBox Linux Additions
    virtualbox-guest-x11.service                                   loaded active exited    LSB: VirtualBox Linux X11 Additions
    ...

make a service

first. cd /etc/systemd/system/ and
make /etc/systemd/system/vboxadd-sharedfolder.service

    [Unit]
    Description=VBox Shared Folder Mount
    After=vboxadd.service
    
    [Service]
    Type=oneshot
    ExecStart=/etc/rc.local
    
    [Install]
    WantedBy=multi.user.target

second. load the service.unit

    $ sudo systemctl load vboxadd-sharedfolder.service
    $ systemctl list-unit-files     

third. enable service

    $ sudo systemctl enable vboxadd-sharedfolder.service 
     ln -s '/etc/systemd/system/vboxadd-sharedfolder.service' '/etc/systemd/system/multi.user.target.wants/vboxadd-sharedfolder.service'
    $ systemctl list-units     

fourth. start service

    $ sudo systemctl start vboxadd-sharedfolder.service

if fail to start service

     $ sudo systemctl start vboxadd-sharedfolder.service
     Job for vboxadd-sharedfolder.service failed. See 'systemctl status vboxadd-sharedfolder.service' and 'journalctl -xn' for details.

you check the status.
