DHCP vs. SYNCDHCP in rc.conf

[Patrick M. Hausen]

Hi all,

from reading the docs I think that SYNCDHCP is supposed
to wait for dhclient to finish and that there should not be
another difference.

But then why does

	ifconfig_em0_name="inet0"
	ifconfig_inet0="SYNCDHCP"

in rc.conf lead to the desired result while

	ifconfig_em0_name="inet0"
	ifconfig_inet0="DHCP"

doesn't?

		ifconfig_em0="DHCP"

works as it should but renaming and configuring via DHCP
works only if combined with SYNC.

Reading /etc/rc.subr did not help ;-) I simply don't get it.

Thanks
Patrick
