On supported Linux kernels 2.6.9 or greater, the MVFS has the
following limitations:
A chroot operation to a directory in a view context is unsupported
The NFS root file system type is unsupported
View-extended naming of objects not in a VOB is limited to directories
and symlinks. After a view-extended pathname traverses a mount point into
a VOB, all view-private and VOB objects are accessible. For example:
/view/viewtag/etc/motd (a plain file) cannot be accessed
and returns an EACCES error
/view/viewtag/tmp can be listed as a directory,
but you cannot create files in it
