rdist'ing files

[rusty wright]

People who worry about security say that you shouldn't have things
like your OS version and unix flavor in your login banner so I changed
my default gettytab entry to be

default:\
	:ap:fd#1000:\
	:im=\r\n:\
	:sp#1200:

Voila!  No more magically changing gettytab.  (Note to Sun sysadmins;
this doesn't work 100% on Suns as telnetd has the "im" hard-wired into
its code.)
