I am not sure if that is on purpose, but it can lead to some confusion if one got changed but not the other. Oops. Not intentional, just an erroneous sed script. Fixed in r344315. > On another note, is there a reason to use chrony instead of ntpd if using the AWS ntp source, ie. 169.254.169.123? Nope. Chrony is what Amazon uses and it's what they recommend for anyone starting from a blank slate; but I discussed this with them and they agreed that since we ship with ntpd already installed it makes far more sense to use what we already have. -- Colin Percival Security Officer Emeritus, FreeBSD | The power to serve Founder, Tarsnap | www.tarsnap.com | Online backups for the truly paranoid
