I don't think anybody using Linux-VServer (or containers in
general) is really interested in having a daemon running
which requires hardware access and total system control.

There is already uselessd and other approaches to mitigate
the fact that most distros have no taste when it comes to
init or audio daemons :)

Last time I checked out LXC, it took me 15 seconds to reboot
the host from inside a container. But yes, there are other
options as well, take your pick.

RHEL 6 has EOL 2023, so that should give you some time.

I'm pretty sure there is, not sure how much you need to
lower the security though to make that work.

I think the main problem is that systemd doesn't do proper
logging when something goes wrong, an so it becomes very
tricky to debug.

If you tell me what fails and why it fails, then it is
probably very simple to add this or that exception to the
Linux-VServer patches to "make it work".

All the best,
