This is what my shell looked like, more or less:
$ su -
# /sbin/service cups start
# cat /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost
It said "Starting cups:", but the "[ OK ]" did not appear; I recieved no warnings, however. And my /etc/hosts file does contain that line.
