Take a look into /etc/init.d.  Scripts there have a start, stop, and 
restart command.  Some have reload and other options.  The system uses 
these during init and shutdown.

/etc/init.d/network restart

will restart the network, however, if all you change is /etc/hosts, that 
is not at all necessary.  The software will notice the change and reload 
as needed.

Restarting apache will not cause loss of data, so that's safe.

Bind can be refreshed without incident with 'rndc'.

Essentially everything except the kernel can be restarted in Linux 
without having to reboot.  Remember, its not Windows.
