Everything went well after upgrading my Ubuntu LTS installation to 10.04 LTS until I noticed that apache and lighttpd won't come up after a system reboot.
I thought it might be a small hickup with the upstart-migration.
Well, turns out it wasn't: In /var/log/boot.log i have found
Cannot assign requested address: make_sock: could not bind to address
Yep. Ubuntu wouldn't bring up my virtual network interfaces on time…
Gladfully someone else had this problem before.
