Red Hat Bugzilla – Bug 51280
pump and dhcpcd handle the DNS search path differently
Last modified: 2008-05-01 11:38:00 EDT
When using pump as the dhcp client, it creates the search path for
/etc/resolv.conf by first using the entire domain passed to it by the dhcp
server, then progressivly stripping off leading parts until only the
registered domain remains.
With dhcpcd, it only puts the domain that is passed via dhcp in the search
For example, my laptop at work is in the wdhq.scyld.com domain. Under
pump, the search line was "search wdhq.scyld.com scyld.com", but with
dhcpcd it is just "search wdhq.scyld.com"
This is a regression from previous RHL versions that can have wide ranging
effects. Anyone who expects a machine, that is not in their nth level
domain, to be available via a simple host name will have problems.
This defect is considered SHOULD-FIX for Fairfax.
My current resolv.conf has 'search redhat.com devel.redhat.com', so it appears
to be fixed.
