[maemo-developers] [maemo-developers] Re: Span filesystem across both SD cards?

[From: sebastian maemo]

Please Jon, expand it a bit, por favor. I've just bricked my device and
reflahed it again trying to symlink "anyway I need".

Maybe it's not a question for developers-list, but Nokia didn't thought that
128M wouldn't suffice me enough to install all apps I'd like for my device.

When I bought N80 phone, I found a very useful and logic feature: when you
install a new app, the application manager asks you whether you want it
installed over your tiny phone memory, or over your large GB memory card.

For don't-know-what-reason Nokia failed to make this feature available on
his 770. They just let me create a 64M swap file that helps, but not that
much.

So here I am, trying to make things work. I've learned how to create
partitions with sfdisk (not so friendly as fdisk), format them with
mkfs.ext2 (that was easy), and mount and unmount them at startup and
shutdown via init.d scripts (that was the worst one).

And now that I've learned all that much, I created the wrong symlinks: I
cp'ed /usr to the MMC, and then made the wrong link: ln -s /media/mmc2/usr
/usr. Yes, now I know it should be the reverse way, but do not understand
why.

My device is just now reflashed. Before reflashing it again and again, could
somebody tell me what should I do right now, before installing any apps,
what to do to be able to install them on the MMC instead of on the 770's
internal memory.

Does anybody know what I'm talking about? Am I the first guy who dares such
a naive question? Don't you get pretty soon the no-more-free-memory
advertisement after installing octave and abiword? Wouldn't you like to
install anything you like and more?

Why should it be so difficult?

Salut.
Sebas.
