Well, it's my initramfs that's attaching everything. Although I left
udef-extraconf out of my build, it's included in the initramfs, and the
automounts that it does survive the switch_root.

My bottom line is that I need to use different mount options. Rather than
try to prevent my initramfs from automounting, I think I'll just supply my
own replacement mount.sh script, which uses the options I want, and adapt
the rest of my system to use the default mount locations /media/sda1, etc.
