I'm thinking more of situations where you want to access the filesystem
data for two different access methods, say, local and NFS or NFS and SMB.
others have basically said "don't do that" and they have good reasons,
however, in many situations (typically small installations) it's
reasonable and expedient.
another big thing that it gives you is that backing up the filesystem
is possible with whatever backup system you want, without having to use
