Hi Joe,
your error is due to oracle user permissions on filesystems.
Non-root users are permitted to run df against mounted filesystems, but they
must have execute permission on the parent directories of the mount.
In your case, oracle user is granted to run df against /boot filesystem but it
needs execute on /boot/efi.
To correct the problem:
# chmod go+x /boot/efi
However, a better workaround is to add oracle user to the disk group
# usermod -aG disk oracle
in order that /boot/efi is not readable to all users.
Greetings,
Alessandro

This doesn't appear to be causing any issues but it does bug me a bit. I can't
find much online about the error other than the grub file down that tree is
needed for booting.
