Comment 7 for bug 1042930

i was actually wondering since we switched to live images if we shouldnt better hide the SD altogether from the partitioner, the main reason to switch to arm live images was actually to avoid any usage of the SD card as rootfs device, simply because of the less than sufficient I/O performance on the SD ..
while you technically *can* install to SD, this install variant is super fragile, i.e. it might have happened that your going back actually selected to format the partition when going forward again which in turn might have triggered partman to wanting to rewrite the partition table for whatever reason.
all the installs to source devices i did over the last 5 years were definitely always a matter of luck if they worked or not in the end.

installing to SD shouldnt be a QA usecase at all imho and we should oprevent the user from falling into that trap
