+ This feature might break your tool of choice to flush the scrollback + buffer, e.g. clear(1) will work fine but Debian's clear_console(1) + will be broken, which might cause security issues. + You can use the escape sequence \e[3J instead if this feature is + activated.I'd recommend that patch get to clear_console() first, having it use the new escape sequence, if it isn't supported, shouldn't cause any problems, right?doko: would you consider, pretty please with a cherry on top, applying the patch I've sent to this bug? The privacy/security issue is pretty minor and applies only to a tiny fraction of users, but I understand why Greg is reluctant.
