Thank you for reminding me of that. You might be right that it is was
a developer's choice, but if so it was a very poor design decision.
The benefit of avoiding an fsck is quite modest, especially with
journaled file systems. And, unless there's something I'm missing, a
sync'd flash filesystem is unusably slow on the Freerunner.
Here is an example of how I installed SHR onto a free partition on my
SD card today:
zcat openmoko-shr-image-*-om-gta02.rootfs.tar.gz | ssh -v
root at 192.168.0.202 tar -C /media/mmcblk0p2 -xf -
With "sync": All day to untar the distribution (no exact time, xfr canceled)
Without "sync": 570 seconds to untar the distribution
