vboxvfs file integrity problems?

[Nicholas Papadonis]

I compared the results between configurations of same directory tree.  Using mounted filesystem with vboxvfs, using filesystem directly on Mac, using NFS mounted filesystem.  All of the same data.

It appears the results over the vboxvfs driver mounted filesystem differ in that vboxvfs mount is missing the “nlink=X” field.  size is also missing, but I’m assuming that’s expected as it’s missing on the nfs mount as well.

$ diff mtreenfs-mount.txt mtreeonmac.txt|more
< branches        type=dir nlink=2 time=1547439167.000000000
---
> branches        type=dir nlink=2 size=64 time=1547439167.000000000

diff mtreenfs-mount.txt mtree-fbsd-vboxvfs.txt |less
< branches        type=dir nlink=2 time=1547439167.000000000
---
> branches        type=dir time=1547439167.000000000

Perhaps the missing nlink is the problem?

Thanks
