we should absolutely remove it if a) we're aware it causes problems and b) we think it makes sense to do it another way. the diff in your previous mail is actually better anyway - the info i was missing was i didn;t realise ifconfig got invoked separately for every line in hostname.if. > > > > we can;t just say order matters, but not provide any guidance. having > > said that, i think the text "The packed formats are converted", which i > > think deraadt added, was meant to address something like this. maybe he > > remembers? > > Well, hostname.if is simply a mechanism to script ifconfig invocations.
