When I looked into the source, I saw that it does an fsync on the underlying
partitions. So I am not so sure, if it really does no harm. To my knowledge
all block devices go through the buffer cache. Don't they?

That's what I do at the moment. But I do not really like it because my /boot
filesystem now resides in a dos partition, where I boot from. I should like
to have a self-contained linux system
