[lug] Protecting Mount Points

[David L. Willson]

Could you remove the directory and define it in auto-mount/auto-fs, instead?

And if you are on an obsolete UNIX that has questionable support for extended file attributes and virtually no way to manipulate them from userland?

Subject: [lug] Protecting Mount Points 


I want to protect some mount points from being written to if an NFS mount were to fail. I think I can do this by setting the mount point to be owned by root and writable by no one. When the NFS export is mounted the mount point will take on the permissions of the export allowing the proper users/groups to write to it. I am about to set up a quick test to verify this but I was wondering if anyone already knows if this works or a better way to accomplish the same? 


Regards, 
Will
