Actually, if you're not going to use VFAT, I'd use ext2. It's going to be about 20% or so faster because it won't be doing the journaling that ext3 does and the journaling could shorten the lifetime of the SD card. ----Steve _______________________________________________ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
