I'd start at the source. Give yourself POSIX-style access to the files
to start with. 'cp' will preserve that access. 'cp' and many other
utilities don't take ACL permissions into account. They are silently
ignored. For whatever reason, it looks like your source file has no
POSIX permissions for user, group, and other. Fix that with 'chmod'
and I think you'll have solved your problem.
I suppose that my issue is that I can look at the source file, use vi on
it, cat it etc despite the fact that it doesn't appear to have any
permissions. Copy the file and I now don't have permissions on the file
at all. In other words when I do CAT, it's clearly checking more than
just the posix permissions otherwise I wouldn't be able to look at the
contents. But the CP isn't then copying that information. If CAT failed
to open the source file with permission denied because of the lack of
POSIX permissions, then the target having no permissions seems
reasonable as you then get the same behaviour on the target. But since I
can read the source, it is checking more than just the POSIX
permissions, it seems wrong to me that CP isn't taking notice of that too.
