/sbin/mount.vboxsf: invalid option -- 's'

[cdragon]

When I try to have autofs mount a vboxsf share in the same way that's worked for years, I now get the following error:

Code: Select all

sudo automount -f -v
Starting automounter version 5.0.8, master map /etc/auto.master
using kernel protocol version 5.02
mounted indirect on /mnt/auto with timeout 5, freq 2 seconds
ghosting enabled
attempting to mount entry /mnt/auto/hostdownloads
>> /sbin/mount.vboxsf: invalid option -- 's'

I believe the problem is explained in this thread. Basically, autofs always passes the -s option to mount and mount used to only pass the -s option on to nfs mounts, but as of some recent update (not sure when but sometime in 2015), mount passes the -s option to all mount helpers, including /sbin/mount.vboxsf. In the thread above, they're talking about mount.ntfs-3g also balking at the -s option being passed to it, and the solution they decided on was to update mount.ntfs-3g to accept -s. So I propose that mount.vboxsf also be updated to accept the -s option.

I'm using the latest VirtualBox 4.3.28 with Lubuntu 14.10 and the mount version is 2.25.1 after updating with 'apt-get upgrade'. I guess it's possible this has already been fixed in a VirtualBox development branch but I'm not sure how to check that.

Is there any other way I might fix this problem?

In case anyone else wants a solution, for now I've "solved" the problem by automounting cifs network shares to the local machine rather than virtualbox shares.

Thanks for the report. This should be fixed in trunk (meaning 5.0.x) will backport to 4.3 later.
