If failed to mount /sysroot, triggering OnFailure= dependencies
of initrd-xxx.service, then dracut-emergency will be started by
systemd and enter into emergency shell.
Here add a judgement in dracut-emergency. If user specify
"action_on_fail=continue", continue though mount root failed.
Otherwise enter into interactive shell.
v1-v2->
action_on_fail function can't be used directly here, discard
it. Instead add a judgement to handle this.
