[yocto] Switching from udev to busybox-mdev causes errors mount: mounting proc on /proc failed: Device or resource busy

[John Smith]

Dear list,

when using busybox mdev instead of udev, I get the following erros on startup.

[..]
INIT: version 2.88 booting
mount: mounting proc on /proc failed: Device or resource busy
mount: mounting sysfs on /sys failed: Device or resource busy


What further steps do I need to edit for a clean boot? I only set VIRTUAL-RUNTIME_dev_manager = "busybox-mdev" in local.conf

Best,
John
