One should note that this is a workaround for something that looks
like a resolver bug to me.
Several daemons (among them sendmail and httpd) apparently do
something like:
char hname[VERYLONG], *absname;
struct hostent *me;
gethostname(hname, VERYLONG); /* Get my name. */
absname = strdup(hname);
strcat(absname, "."); /* Force it into the root domain. */
if ((me = gethostbyname(absname)) == 0) {
complain("Myname (%s) does not exist.", hname);
bailout();
}
This works fine as long as DNS is in effect. If however /etc/hosts is
queried to resolve myname, this fails if there's no entry available
_with_ the trailing dot.

Never trust an operating system you don't have sources for. ;-)
