Что это всё такое и надо ли оно на обычном компе? (99% лазанье в инете). Что будет, если отключить эти самые cgroups? Ещё заинтересовали пункты subvol. Что это такое, зачем оно и можно ли отключить? Вместо одного корня и одного свопа у меня монтируется вся эта кавалькада, зачем всё это??? На всякий случай fstab:
