I just noticed this thread — this is more or less the problem I am
trying to deal with.  On my VPS running Debian I moved most of my
services into a Guix container.  The directories with important state
(e.g. user homes with Maildirs inside, gitolite repositories, some
static files being served over HTTP) are shared with the host.  User
ids of some daemons inside the container are set to be the same as
outside.

The container communicates with the outside world through a veth pair.
The host has some internet-facing ports forwarded to the container.  If
you're curious, here[1] is the code that spins up the container.  It is
called from an init script (managed by systemd but the script itself is
sysV-compatible).

The overall result is somewhat messy and I would like to already have
everything running under a full Guix system.  Meanwhile, I've been
stuck in this transition for over a year now — it's probably just as
inconvenient as insecure.

A full system would allow one to utilize
- the unatended-upgrade-service-type
- and the `guix deploy` command.

So — to all who are yet to do such a migration — my suggestion would be
not to set up a Guix container the way I did it.  If you have a second
server — Felix' approach is probably the best.  Otherwise, a VM with
Guix inside could be a a more practical solution than containers — as
long as the server you're going to run it on has enough RAM

Best :)
