(Because as you create the fs image, the storage device parameters may make a difference to how blocks get allocated.) The reason why I talk about making it work automatically at mke2fs time is that the vast majority of created file systems (where a specially created fs by a handset vendor counts as "one", even if it then gets stamped on millions of devices), the end user is someone naive/oblivious, so the right thing *has* to happen by default in the common case of running mke2fs on the storage device where the file system gets used. - Ted -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
