I can't agree more (I always go out of my way to have excellent error reporting in my own code), but I think that what is going on here is that -1 was interpreted as an 'errno' - and strerror was used to print a human readable description. If you pass -1 to strerror it returns "Unknown error -1", because -1 isn't a known errno. Ie if you pass 1 to it, it will say "Unknown error 1". The real problem therefore seems a bug in the code where the return value of a function that is either >= 0 on success and -1 on error is interpreted as errno. ___ systemd-devel mailing list systemd-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/systemd-devel
