It is an UEFI system, but NOT SecureBoot enabled. I understand the reasons why your might not want to do this for SecureBoot enabled systems (I might not like them, but I do understand them).
In this case, I get the capability I want by making an ext2-formatted partition on the not-easily-removable persistent storage device and putting the ISO images there. It struck me that it should be possible to use a UDF formatted partition - mainly because I sometimes have to rescue broken systems, and it is convenient to be able to write out ISO files that are larger than 2 Gigabytes on removable media that are 'cross-platform' readable and writeable.
