My mistake - yes, I should have thought that one through. I take from
this thread that the loss can be up to 50% of battery life - is that
accurate? It does change my opinion significantly, but I'd be willing to
assist in some "power/time trials" with various commit intervals to see
if we can bring it down to a reasonable factor... Personally, I'm of the
"ext3 for all 'potentially naive end users'" school of thought, in that
the /worst/ thing that could happen is for a "PNEU" to hit: "Filesystem
corrupted, enter root password for maintenance:" at startup. Some
"paranoid enough" rc scripts with dialog(1) (or even an /etc/rc.d/rc
using GDK-framebuffer?) might help ease the burden on this...?
