Operations such as mkfs fail on devices that are not switched to the actual rootfs before switch_root is called. The kernel interprets these devices as still being used even after unmounting and errors such as below are seen when the target is fully booted root@v1000:~# umount /dev/sdb1 root@v1000:~# mkfs.ext4 /dev/sdb1 mke2fs 1.43.8 (1-Jan-2018) /dev/sdb1 contains a ext4 file system last mounted on Wed Nov 28 07:33:54 2018 Proceed anyway? (y,N) y /dev/sdb1 is apparently in use by the system; will not make a filesystem here!
