Oh and I should perhaps add: With allow-auto AND the sleep: all services find their addresses and start up correctly.
With allow-auto WITHOUT the sleep,... well when waiting for my script to restart the networking, then of course no service (but ssh, which I've restarted from the script) was running correctly. But before I had my script in place, I got back access to the machine by simply n-times rebooting it via Ctrl-Alt-Del signal from the hosters web-interfaces... and after a so 5-15 reboots it usually worked once to at least have ssh back... but even then only *some* services (luckily including ssh) were running... others (especially bind and apache) always failed then too (probably because IPv6 was still not yet in place but only IPv4, which explains why sks started up, as it doesn't fail when it cannot bind to all addresses). With allow-hotplug (and without the sleep) I also had some services not staring up (as I wrote already last night). Cheers, Chris.
