I tried cgroups as a bigger hammer to throttle I/O, but it didn't help

I take it back: it did help a bit. Although I still saw lots of I/O
errors from the kernel, the rsync was able to finish successfully.
Previously after enough errors accumulated, the kernel would re-mount
/mnt/sysimage/boot as read-only and my rsync would fail, but with the
cgroup throttling down writes, it was able to finish copying and the
mount remained read-write the entire time.
With a quick update of the UUIDs in /etc/fstab and /boot/boot.{cmd,scr}
the Trimslice is booting F20-Beta-TC2 from the SSD now.
Just out of interest, what make/model SSD are you using? My past
experience shows that, contrary to what you might expect from supposedly
standardized technologies, serious compatibility issues are not at all
uncommon.
