I'ts most likely a fallout, but I wonder why. To get this behaviour moutn would have to add all the options it finds in /proc/self/mounts to the command line. Added the util-linux-ng list to shed some light on this, but I suspect I'll have to change xfs_fs_remount to check if the option passed in is identical to the one we already have and only reject it when it changes due to this mount(1) dumbness. -- To unsubscribe from this list: send the line "unsubscribe util-linux-ng" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
