no network hotplugging with dhcpcd 5

my system is configured with

INTERFACES=(eth0)
eth0="dhcp"
DAEMONS=(@network @netfs dbus hal kdm)

with dhcpcd 3.2 i have network hotplugging working ok. ie if i plug the cable after pc is up or if i unplug and plug again the cable i have internet after few seconds

with dhcpcd 4.X and 5.X i have internet only if the computer booted with the cable in. if i unplug and plug back the cable i have to run manually dhcpcd -k eth0 && dhcpcd eth0 to connect again

why does not dhcpcd 5 work ?

Re: no network hotplugging with dhcpcd 5

dhcpcd-4.x and 5.x have their own hotplugging support and relies on the kernel to correctling send netlink messages saying CARRIER UP and CARRIER DOWN. I guess your network drivers does not support this, and relies on other methods.

man dhcpcd.conf for details on disabling the link detection.

I've experienced issues too with dhcpcd new version, so i use since then oldschool dhclient.
