Even if b) is the final goal I would first do a) and mark the new option --enable-support-mtab as deprecated from the beginning. Could be interesting to see who would ever use this option and because of which reasons. About changing the default: We could add a warning somewhere to a non-critical tool when printing human-readable output, like lsblk: "warning: deprecated /etc/mtab file ingnored" ... just to remind people to fix their system/scripts. cu, Rudi -- To unsubscribe from this list: send the line "unsubscribe util-linux" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
