My test partitions share a single /home/ and single /usr/local/ partition, are installed with recommends disabled, and have installed only one DE besides the default IceWM, so have modest space requirements.
My strategy is a main system, big, home plus root, and a small extra test/rescue system (single partition), 9..15 GB. Once done testing, I upgrade the main system, not switch.
I had only three on my main system for a number of years, current, next, test. problems common to betas made me add a fourth, to keep the former longer and/or opportune more than one "next". Now with so many PCs here one wouldn't expect that to matter, but this is using RAID, while the others save one is not, and the one that is is pretty much different from this.
USB is/are a(re) different bus(es), which is/are subject to different device enumeration order and thus different device name assignment. Thus, I never do USB HD boot.
Just use labels or uuids.
I know that, and you know that, but not every rescue context is helped by those, in particular, Grub*.
I use eSATA when I need to boot from an external HD. That way, the BIOS is able to assist when necessary with the problems variable device names can cause during rescue operations.
No such problems - there are no variable names if you choose the correct ones ;-)
Not usually the first thing done in rescue mode is
fdisk -l | or | parted -l
No UUIDs or labels in those. So in context of anyone needing help being instructed, the very first result is consternation. Other rescue tools often have similar limitations
But gparted sees and creates labels. And in the context of having an external disk booted over eSATA or USB, it works :-) -- Cheers / Saludos, Carlos E. R. (from 42.3 x86_64 "Malachite" at Telcontar)
