И, что тоже немаловажно, большинство пакетов придется пропатчить, чтобы
они правильно сбрасывали эти capabilities. Например, в том же mtr сейчас
производятся действия вида setuid(getuid()); вряд ли такой вызов приведет
к сбросу capabilities, в результате чего mtr будет работать в более
привилегированном режиме, чем раньше.
