I ran the following 2 commands on my VPS box and now it boots without starting any software at all. According to rcconf it's still supposed to start my chosen software (ssh etc.) but it doesn't.

update-rc.d vz defaults
update-rc.d vzeventd defaults

I already tried removing them again with

update-rc.d -f vz remove
update-rc.d -f vzeventd remove

But that didnt't change anything.

/etc/rc.local also still correctly lists some scripts I want to run at start-up, but they don't seem to be called either.

I expect the top 2 commands to be responsible, but here's everything I did:

mkdir /var/openvz-dl
cd /var/openvz-dl

apt-get install fakeroot alien
fakeroot alien --to-deb --scripts --keep-version vz*.rpm ploop*.rpm
dpkg -i vz*.deb ploop*.deb --force-overwrite

update-rc.d vz defaults
update-rc.d vzeventd defaults

reboot

A huge part of that failed because I was running it on an OpenVZ VPS which has a shared kernel that can't be altered, so I also had to fix the dpkg like so (it was moaning about wanting to install vzkernel with a package not being found);

rm /var/lib/dpkg/info/vzkernel*
dpkg-reconfigure vzkernel --force
dpkg --purge --force-all vzkernel

But that didn't fix the boot issue either. How do I make my software start at boot again?
