Re: Autofs: Need UID & VFS hook, security notice

[Richard Stallman]

    Additional locks required, for one thing.  You really don't want to do
    this in the VFS; rather as a shim on the block device level.

I am not an expert on these things, so I won't try to argue about
whether this is true.  Supposing you're right, and the best way to do
this job is at the block device level, do you think that is a feasible
approach for solving the problem?
