Hi Christian! Glad to hear from you again! > first of all this is my very first mail here to this list and I am completely > unsure, if I am right here.

I am a > postmaster and managing several mail servers. And for some of them, I really > do have boot issues with Upstart. > > To explain: > > I have many IPv4 and IPv6 addresses for one server. The problem starts with > /etc/network/interfaces. No matter if I put several iface ethX inet(6) static > blocks into the config file or adding post-up/pre-down scripts with iproute, > it happens every two of three boots, that not all of the addresses were set > up correctly.

This gives ample time for any DHCP or heavy static configurations/bridge/bonded/etc configurations to finish, but will continue the boot in case you have listed an interface there that is broken or will never come up. > Here is some header from postfix: > > start on (started opendkim-sign and > started opendkim-verify and > started amavisd-milter) > stop on runlevel [!2345] > > Here you can see missing deps. Amavisd and slapd are missing. Also saslauthd > and I do not know how to solve this. Remember that these are *events*, not dependencies. Anyway, give 11.10 a try, its possible we will backport something to lucid, but no guarantees, as its a rather large change in the way we treat /etc/network/interfaces, and it has not been popular with everyone, as there are some people abusing /etc/network/interfaces and this causes their system to take 2 minutes extra too boot. -- upstart-devel mailing list [email protected] Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/upstart-devel
