Question: What if the custom kernel crashes

[mafischer]

What will happen if the kernel keeps crashing after enabling udm-autoboot.service? Will it auto disable after a couple failed boots?

[fabianishere]

The service will refuse to auto-boot if it sensed that the previous boot failed.

To see how this mechanism works, see

udm-kernel-tools/udm-bootctl
