On the matter, of ext partitions there seem to be some ROMS that use ext2 and some that use ext3. Then there is also ext4. This can be annoying if you want to try another ROM that requires the ext type you don't currently have. I'd really rather not have to wipe the SD card and have to repartition it. Since I know I can use Acronis to format both ext2 and ext3, would it work OK to have FAT32, ext2, ext3, and swap all on the same SD card?
Also, I saw a post that seemed to say Froyo ROMs require just having one big FAT32 partition. That seems rather off to me since I thought Froyo ROMs could use A2SD.
