4484 Add that line, and XEmacs will be happy. 4484 Add that line, and XEmacs will be happy. If your network is unreliable,
4485 such as a Wifi network, you may experience delays but eventually XEmacs
4486 starts up. This may be due to having the lookup order give precedence
4487 to DNS over the hosts file (often lookup order is defined in one of the
4488 files @file{/etc/host.conf}, @file{/etc/nsswitch.conf}, or
4489 @file{/etc/resolv.conf}, depending on OS). See your system
4490 documentation for this configuration. Note that changing the lookup
4491 order is a workaround; there are good reasons to have DNS come earlier
4492 by default. Make sure those reasons are less important to you than a
4493 quick XEmacs startup.
