Was it to take advantage of the features that ext2 provides ? > Romfs should have had a better bootup time than ext2/jffs2/cramfs. Are you sure of this? Do you have actual benchmark data? Also, romfs has some restrictions (owner and permission information) and an inefficient design (pages read from filesystem cannot be executed directly because of 16 byte file header offset).
