Nope, it was very consistent and did not change over time. One oddity is 
that if you access a file (in a particular view (MVFS-speak for branch, 
more or less)) via the 'multi-view' mount

/cygdrive/m/my_view/my_VOB/some-path-to/some-file

you get (consistently) one number for st_ino and d_ino (call it 'A')

But, if you mount my_view to a drive and access the same file in that 
same view via the mount

/cygdrive/r/my_VOB/some-path-to/some-file

you get (consistently) a different number for st_ino and d_ino (call it 
'B').

Not sure if that's important (maybe it's expected behavior?)
