Hello!
I am hacking around with a portable linux media-player. This media-player uses a compressed ramdisk (cramfs) to hold its mini-linux distribution which therefore can't be modified by a user as the cramfs is read-only. I already added unionfs to the firmware and specify the directories in this order: /opt=ro:/progfs/unionfs/opt=rw where /progfs is a writable harddisk partition. There is now a major change in behaviour of the media-player, the harddisk doesn't spin down anymore or more precisely it spins down just to spin up again immediately. This, of course, will kill battery life. Will unionfs always access all directories specified for a union upon a read operation and therefore make the harddisk spin up? Is there a way to change this behaviour? Some way of buffering changes that went to /progfs/unionfs in RAM?
I hope you can help me... :) Greets, Philipp. _______________________________________________ unionfs mailing list [email protected] http://www.fsl.cs.sunysb.edu/mailman/listinfo/unionfs
