The hard limit should be 2.63 since that is supported in all of the modern long term releases from the distros. I’d prefer we not exit processes because we’ve been removing active checks on process starts. mark On Jul 29, 2014, at 9:51 PM, Xuhan Peng <pengxuhan at gmail.com<mailto:pengxuhan at gmail.com>> wrote: We bumped the minimum version of dnsmasq to 2.63 a while ago by this code change: https://review.openstack.org/#/c/105378/ However, currently we still "kind of" support earlier version of dnsmasq because we only give a warning and don't exit the program when we find dnsmasq version is less than the minimum version. This causes some confusion and complicates the code since we need to take care different syntax of dnsmasq of different version in dhcp code (Note that the previous version doesn't support tag). I wonder what's your opinion on NOT supporting dnsmasq version less than 2.63 in Juno? I think we can prompt error message and exit the program when we detect invalid version but I would like to gather more thoughts on this one.
