Re: rsyslog init script breaks after package upgrade

That's surprising me, too. It works fine on my laptop, which uses testing.

I can however confirm this observation. On my server, it says:

The system is running on a virtual server provided by Stato. I do not
have access to the kernel - as in, I cannot (un)load modules or even
choose my own. As far as I know, they are using OpenVZ for
visualisation. At least, the root FS has type "vzfs". uname says:
> # uname -srvmpo
> Linux 2.6.32-042stab078.27 #1 SMP Mon Jul 1 20:48:07 MSK 2013 i686 unknown GNU/Linux

I hope this is helpful.

Kind regards
Ralf
