In fact, now I look at it, ntpd as it stands cannot replace ntpdate for anaconda's purposes, because anaconda calls ntpdate with the -q option, which means "query only, do not set the clock" - obviously, this is appropriate when we just want to test the functionality of an NTP server. ntpd does not have an equivalent option. -- Adam Williamson Fedora QA Community Monkey IRC: adamw | Twitter: AdamW_Fedora | identi.ca: adamwfedora http://www.happyassassin.net
