Need of commandline to start VM with access to shared folder. Now if I run/usr/lib/virtualbox/VirtualBox --comment win --startvm c252555c-bla-blaI get VM running but shared folders not mounted, and I have to go to VirtualBox GUI manager and manualy  re-select sharedfolders connections. unless the checkbox automount is checked. It has no effect in commandline launch mode.    
Right way to start VirtualBox with shared folders mounted
command line;mount;virtualbox
