This allows creating a container from an existing system store path,
which is especially nice for NixOps-deployed hosts because they don't
need a Nixpkgs tree anymore.
Systemd in a container will call sd_notify when it has finished
booting, so we can use that to signal that the container is
ready. This does require some fiddling with $NOTIFY_SOCKET.
Previously "machinectl reboot/poweroff" brutally killed the container,
as did "systemctl stop/restart". And reboot didn't actually work. Now
everything is fine.
On some non-NixOS systems (for example those using "resolvconf"),
/etc/resolv.conf is a symlink. So let's dereference when copying hasts
and resolv.conf.

With mutableUsers = true, we now ensure that all users and groups that
were created declaratively, are updated or removed
appropriately. Thus, adding a user to users.extraUsers and then
removing it now causes the acoount to be removed from
/etc/passwd. Thus user/group management is fully congruent except that
users and groups that were created imperatively (via useradd/groupadd)
are not touched. We distinguish between declarative and imperative
users/groups by tracking the former in
/var/lib/nixos/declarative-{groups,users}.
With mutableUsers = false, you are now no longer required to specify
UIDs/GIDs for all users. The handling of mutableUsers = true/false is
the same code path; the only difference is that the "false" mode
ignores the existing contents of /etc/{passwd,group}.
The attribute ‘createUser’ is gone. It doesn't really make sense to
specify users that shouldn't be created.
Used to add GI_TYPELIB_PATH and LD_LIBRARY_PATH for gnome shell extensions
or other libraries and services.
Not a great solution but may be the start for further work. Let's make
some cool packages work for now.
Setting "services.lighttpd.gitweb.enable" to true doesn't enable the
required lighttpd modules to actually make it work. The problem is that
"or" and "||" don't mean the same thing: "or" falls back to the second
operand if the first is not defined, whereas "||" is the normal logical
operator. When cfg.cgit.enable is defined, as false, the expressions
don't have the desired effect.
