VPS boot overrides some configuration files

Problem: I bought a new VPS and did some configuration changes (e.g. hostname setting). I’ve installed some software and wanted to test if my settings are boot resistant. And every time the VPS was¬† booting the files /etc/hosts and /etc/hostname was overridden by the defaults of the provider.

Reason: Virtuozzo (the software which virtualises my VPS) overrides those files at every  time the VPS is booting.

Solution: Replacing the files /etc/hosts and /etc/hostname at boot-time.

The following description is applied for Ubuntu 14.04. Both replacements are implemented as upstart jobs.


Copy the /etc/hosts (e.g. /etc/hosts_my) and adapt it to your needs. Then create the file /etc/init/hosts.conf with the following content:

description "restore my hosts"
start on startup
exec cp /etc/hosts_my /etc/hosts


Copy the /etc/hostname (e.g. /etc/hostname_mod) and adapt it to your needs. Then edit the file /etc/init/hostname.conf and change the last exec command to:
exec hostname -b -F /etc/hostname_mod

That’s it!
