The reason this happens is not because of util-vserver, or anything
related to vservers at all, but instead the Debian startup scripts which
clean /var/run on bootup and shutdown. The only way to fix this is to
alter your debian scripts not to do this.

This fails because the Debian startup scripts need to be able to write
to /var/run, so they fail and thus the startup of that server fails.

This isn't a util-vserver bug, and the maintainers of the debian startup
scripts will also tell you that this isn't a bug. Trust me, I've checked
this out, they will tell you that you are trying to do something
non-standard and the cleaning of /var/run is there for a reason. If you
want to make it fail, then you make the startup fail.

The way I solved this was to have mysql listen on the private network
and then I contact it over the network, rather than through a socket. If
you want to use a socket, then you need to be putting that socket
somewhere other than /var/run.
