Well, both work, but the main reason I've made this change is so that I 
can enable lingering on users and run persistent user-specific services.

I've been dropping 0004-remove-user-.service.patch from RHEL's systemd 
packages since RHEL 7.2, when Red Hat bumped systemd up from v208 to v219. 
I haven't encountered any problems with this change.

[systemd-devel] systemctl --user on RHEL -- is this a bad idea

[Jeff Solomon]

Hi,

I would like to use a user service (systemctl --user) with systemd on RHEL7
where it has been deliberately removed.

I've communicated with the RH dev who made this change who reported that I
could restore the /lib/systemd/system/user@.service file and mostly
everything would work.

I don't care about having the user service exist only when the user is
logged in, as I will enable lingering on the service and I want it to be
running from boot to shutdown.

I've found that I can run:

systemctl start user@foo

to start the foo user's service and that works, but on other systems
(Ubuntu) where user services are officially supported, the user service is
automatically started when I run:

  loginctl enable-linger foo

whereas on RHEL, running this command does not start the service.

I can imagine writing a tiny additional service on RHEL that will start the
user service using:

ExecStart=/usr/bin/systemctl start user@foo

but I'd rather make lingering officially work on RHEL to the extent that
that is possible.

Two questions:

1) Any idea how to make lingering work such that the user service is
started automatically on reboot

2) Is it a really dumb idea to try to make this work on RHEL7?

Thanks!

Jeff
