OK, now it makes sense to me -- mostly.

I have reviewed my permission requirements, and I can live with this:

   # ls -adl /usr/local/home/mds/mail
   drwxr-xr-x   19 mds      mds          4096 Jan 28 10:29 
/usr/local/home/mds/mail

This allows amcheck to run _without_ errors, even _without_
/usr/local/home/mds/mail/.amanda.excludes , which is what I wanted.

Nonetheless, I remain confused, since conf uses:

   exclude list optional ".amanda.excludes"

So, even though it is `optional', amcheck *must* have permissions
adequate to see whether or not the `optional' file exists?

Would that condition impact the actual backup itself?  Or, since it runs
as superuser, it would have access to the exclude file, and everything
would be OK?

Am I getting closer to understanding this?
