OK that seems logical.

If this goes in, make a mental note to patch udev default rules
too, because currently they look like this:

rules.d/60-persistent-storage.rules:KERNEL=="mmcblk[0-9]",
SUBSYSTEMS=="mmc", ATTRS{name}=="?*", ATTRS{serial}=="?*",
ENV{ID_NAME}="$attr{name}", ENV{ID_SERIAL}="$attr{serial}",
SYMLINK+="disk/by-id/mmc-$env{ID_NAME}_$env{ID_SERIAL}"
rules.d/60-persistent-storage.rules:KERNEL=="mmcblk[0-9]p[0-9]",
ENV{ID_NAME}=="?*", ENV{ID_SERIAL}=="?*",
SYMLINK+="disk/by-id/mmc-$env{ID_NAME}_$env{ID_SERIAL}-part%n"

(I guess Android also has this kind of rule baked into its "big init"
process that handles also what udev normally takes care of.)

Anyway:
