OK, I've flashed the ROM (with CardFS), and I'm liking it. There is a little wonkiness when removing and inserting the SD card (for example, although all the apps [dis|re]appear like they're supposed to, I get two tabs each for PIM and Games (of which, one is blank). But otherwise, it's not that big a bother for me to leave the card in--I can always SCP the files I need out and back.
So. . . my question for now is. . . to install apps to CardFS, do I only need to do a "-d sd" as usual? Is this not going to install to /opt/QtPalmtop/, etc.., like in the stock OZ ROM? I noticed that the files are in /mnt/card/bin, as opposed to mnt/card/opt/QtPalmtop/bin. Thanks for your help. . .
