Subject: Re: Need help with mount and /etc/fstab
I think that it's encouraging that this conforms to another system.

What about the contents of those directories? I'm thinking that
permissions there might be restrictive. chmod -R will do a recursive change.

Let me know.

P.S.
#1 I doubt that will help.
#2 sounds dangerous. I wouldn't do unless I had a backup to restore with.
#3 Who knows, but I doubt it.
