All, Not sure if this is kernel or dhcpcd related, but after update to 4.15.4 tonight ArchLinux clients on LAN receive new IP from server (which have not changed in 4-years before), and server DNS zones are not updated, but instead retain the old IP. The error is a general "Has an address record but no DHCID, not mine." (which may be a holdover from an earlier bind failure) Regardless, this has never before caused dhcp4 to issue a new address while retaining the old in the zone files for any Arch client in the 50 or so kernel updates before 4.15.4. (and this was consistent for each Arch box after the 4.15.4 kernel update) Take it for what it is, just be aware if you are admining a remote Arch box that gets its address via dhcp, you may end up with a new address while the old is still reported by nslookup. Just strange... No replay necessary, unless you have an idea of what changed between 4.15.3 and 4.15.4 that may cause this behavior. -- David C. Rankin, J.D.,P.E.
