Description

A recent update broke a certain instance of lighttpd I was using for local development with the error:

2017-10-27 10:09:55: (configfile.c.1470) a default document-root has to be set
2017-10-27 10:09:55: (server.c.1218) setting default values failed

I traced back the cause to the fact that now var.CWD is the empty string:

[mbeniamino@mbeniamino4 ~]$ lighttpd -f /dev/null -p
config {
    var.PID = 7703
    var.CWD = "" 

}

I don't think this is the intended behaviour, is it?

lighttpd version: lighttpd/1.4.47
