Re: [Ipodlinux-devel] ppc ipod questions

[Bernard L. <le...@bo...>]

Hi again,

I'm not 100% sure about the partition on the iPod, I haven't
experiemented that much (infact I'm just using the standard layout on my
win iPod).  I imagine the bootloader is quite sensitive to changes in
the partitioning.  I believe however that if "data" partition for a mac
iPod is converted from HFS+ to FAT32 it will still work with iTunes and
the Apple firmware.  Can anyone confirm that?

Anyhow except for experimentation I would suggest leaving the partitions
as they are currently.  Until an alternate usable firmware is available
being able to revert to the Apple firmware is very useful (required for
me!).  In the long run using an ext3 filesystem might be interesting to
get better usage of the available disk space.

Regarding the power-off situation the only real danger is is the reset
function of the iPod.  The lower battery power situation should be easy
enough to handle (eventually :) by the kernel.

cheers,
bern.
