Hi Thomas,

I'm currently working on integrating NM properly into resolvconf and
ifupdown (resp. the other way around). Looking at resolvconf it seems
that if I call dhclient manually,
/etc/dhcp3/dhclient-enter-hooks.d/resolvconf is called to update
/etc/resolv.conf. For NM this means, that it simply has to check if
/sbin/resolvconf exists, and if so, don't touch /etc/resolv.conf.
Eveything works automatically then.

But if I use ifup for an dhcp enabled interface, resolvconf seems to be
called twice: once by ifupdown:
and then by dhclient:
Is this observation correct? Or does ifup call dhclient with a special
parameter to not call /etc/dhcp3/dhclient-enter-hooks.d/resolvconf?

I fear, if I integrate support into NM to call the scripts in
/etc/network/if-*.d/ , resolvconf will be called twice. Or is this
absolutely ok, and just a bit a waste of resources?

Hope you can help me with this.

Unix IS user friendly... It's just selective about who its friends are.
