15 Slightly off...

17 ifplugd is used to bring a network connection up/down when the network
18 device is plugged in or unplugged. So the OP doesn't want net.eth0 starting
19 at boot automatically because the cable might not be plugged in at the time.
20
21 Unfortunately that's as much as I know about ifplugd. I do know that the
22 gentoo network scripts will ensure that the "provide net" flag is defined
23 that ntp-client relies upon to do it's thing.
24
25 What I don't know is how integrated ifplugd is with the gentoo network
26 scripts, if it too ensures the "provide net" flag is specified. Nor do I
27 know if, upon cable switching from eth0 to eth1 for example, the network
28 services that were previously tied to eth0 would be restarted to now use
29 eth1...
30
31 I'm willing to gues that in the OP's case the ifplugd is not setting the
32 "provide net" flag correctly and/or it is setting the flag before a cable is
33 actually connected. In any case it's probably down & dirty with the gentoo
34 networking scripts to figure out how to get the timing to work right...
