Note that the errno message is misleading: it was last set when trying to find a restart state file.Thanks to Marcin Krol who found the issue and helped me debug it.
You can record his contribution in the git history if you'd like, e.g. Reported-by: Marcin Krol <his-e-mail> Not sure there is a standard tag used for people helping with debugging. The patch itself looks good to me, although thanks to use of these helpers some code paths will report an error twice. Reviewed-by: Ján Tomko <jtomko@xxxxxxxxxx> Jano
