Забыл еще один параметр,  не знаю как он повлияет на наши livecd
CONFIG_OVERLAY_FS_REDIRECT_DIR
Без него
level=warning msg="Not using native diff for overlay2, this may cause
degraded performance for building images: kernel has
CONFIG_OVERLAY_FS_REDIRECT_DIR"

> Я так понимаю, большинства параметров в наших ядрах 5.4 ждать не стоит.
