Calling vlogmsg() twice from logmsg_perror() results in this beauty: $ ./pasta -i foo Invalid interface name foo : No such device because the first part of the message, corresponding to the first call, doesn't end with a newline, and vlogmsg() adds it. Given that we can't easily append an argument (error description) to a variadic list, add a 'newline' parameter to all the functions that currently add a newline if missing, and disable that on the first call to vlogmsg() from logmsg_perror(). Not very pretty but I can't think of any solution that's less messy than this. Signed-off-by: Stefano Brivio <sbrivio@redhat.com> Reviewed-by: David Gibson <david@gibson.dropbear.id.au>
