Here's a recipe that works (at least, on my iMac with Ubuntu 14.04): I sincerely hope some other poor soul gets some value out of this.

Well, I spent a second whole day on it and now I've cracked it. If I can get this solved I will place a clear guide on the web somewhere! Can boot, rEFInd loads, there is an option to boot ext2_圆4.EFI(?) but no Ubuntu/vmlinuz.Copied ext2_圆4 to /EFI/boot and /EFI/refind.

Put rEFInd on a another, FAT32 partition which contains /EFI directory.

USB disk has ext2 /boot partition (with vmlinuz image on it), and ext4 / partition with the rest of Ubuntu 14.04 installed.

However, I think I must be close to cracking this and hope somebody can point to a step-by-step guide somewhere. I'm a bit stuck at this point, and the next steps will have to be a detailed study of bootloaders and EFI. I have an ext2 /boot partition on the same disk, and copied ext2_圆4.efi into the /EFI directory, but no go. So, I've managed to get rEFInd installed on a partition on the external drive but it does not detect the Ubuntu installation. However, the common thread appears to be using rEFInd to rejig the boot options. I have Googled extensively and I'm sure it's possible to get the Mac to boot it, but the instructions I've found have been either too vague ( Installing Ubuntu on and External Hard Drive and boot in a Mac) or in one case, too complex ( ) to make much sense. However, contrary to some assertions here and elsewhere, after restarting the result is not detected by the Mac as bootable.

I can easily create a bootable USB stick and use that to install Ubuntu 14.04 onto a properly partitioned USB device. you will not need to hold down the alt key the next time you restart your mac.I wish to run Ubuntu on my iMac from external USB storage, either an external disk or a flash drive.

Use one of your other Macs to download the OS installer from the App Store for free.

and actually, since my Mac Mini (with USB 3.0) has an internal 5400rpm hard drive, can't I make such an external SSD boot up drive for the Mac Mini, and boot up my Mac Mini using this SSD from now on, and make the Mac Mini run a lot faster that way?

(I supposed using the Samsung T1 would make the iMac really fast too? That's because I can connect the Samsung T1 to my Macbook Pro and copy files at a speed of 400MB/s) The thing is, how do I make such a bootable drive, when the original iMac isn't working so well? I do have a Mac Mini, a Macbook Air, and a Macbook Pro Retina, running Mavericks or Yosemite, so I do have some Macs to work with in order to set up this external hard drive. Can I now use one of those Samsung T1 SSD USB drive, or a Seagate 2TB external USB drive, or a WD Thunderbolt My Book, and boot up the iMac using this drive from now on? So I suspect the hard drive is not working so well any more. I then rebooted the machine and it took something like 8 minutes to boot up since then. I have an iMac 27 inch, and one summer the room temperature was up to 40C, and I came home that day, and the hard drive was really slow.
