Vagrant is crashing if SMB synced folder is defined, but there no CIFS installed and no Internet is available

Vagrant is crashing if SMB synced folder is defined, but there no CIFS installed and no Internet is available.

There was a workaround back ago for Vagrant's team long inability to implement synced_folder functionality properly, when you could omit the mount point and vagrant would not attempt mounting the share.

It looks like currently there is a terrible hack which seems to try to install CIFS unsolicited, if it is missing in the guest system.

Can we please hack this hack to give an option to NOT execute the capability: smb_install whe we do not want to and just create a share without mounting it?

Is it possible to create SMB share and mount it later on without unwanted intrusion in the guest?
