I am trying to get the core file of this priviledge separated daemon.
# ulimit -c unlinited
write to everyone on / and / sbin just during the test.
i also change sysctl core nosuidcoredump to 0 (despair ..)
I dont have gdb on the machine.... how to get the core of dhclient.
I guess i will (try to) reproduce on a recent snashots, the dhcp
server is dnsmasq.
(i am using it to resolve local hostanmes)
