Hi, The wiki says this: THIS DOES NOT APPLY TO RECENT KERNELS - IN-KERNEL AUTODETECTION HAS BEEN DELETED https://raid.wiki.kernel.org/index.php/Autodetect What does this mean? I ask because [chris@f29h ~]$ grep AUTODETECT /boot/config-4.18.7-300.fc29.x86_64 CONFIG_MD_AUTODETECT=y So it's not deleted? It is deleted? Both? -- Chris Murphy
