I agree, but I'm not sure where the problem is happening.
I _think_ the problem may be related to repeated insert/remove cycles
before the dhcpcd has timed out. I have other problems with the dhcpcd
timeout because I am usually inserting my network card so I can use the
modem in it and the 60 second timeout is greater than the connect time
(and because of some other scripts happening at the same time, such as
my 'whereami' utility) my route sometimes goes west when the network
initialisation finishes after the ppp session starts.
For this reason I actually edited /usr/sbin/dhcpcd by hand (that's the
script that chooses whether you want a 2.2 dhcpcd or a 2.0 one) and set
the timeout to 5 seconds. I don't know any networks where 60 seconds
would be a reasonable timeout for dhcp address assignment - all
instances that I have seen seem to happen in milliseconds.
Cheers,
Andrew.
PS. If you're interested, I have a bunch of scripts which I have
(Debian) packaged up as 'whereami' which allow my system to
auto-configure itself for the locations I plug in at. This works well
for fixed IP now, as well as DHCP which it always worked for.
