initial vfstab support (Solaris like platforms)
initial vfstab support (Solaris like platforms)

Introduce vfstab support for mount.fstab, entries for opts look a bit
weird. Default are '-' so it will end up as a list containing '-'.

I left this to keep 'opts' the same as for normal fstabs.

Example output:

        ----------
        device:
            fd
        device_fsck:
