[gentoo-dev] RFC: News: systemd sysv-utils blocker resolution

[Mike Gilbert]

Hi all, 

There has been a bit of confusion over a change I made recently. I
would like to publish a news item before the relevant version of
systemd is marked stable.

Any suggestions are welcome.

Title: systemd sysv-utils blocker resolution
Author: Mike Gilbert <floppym@gentoo.org>
Posted: ????-??-??
Revision: 1
News-Item-Format: 2.0
Display-If-Installed: sys-apps/systemd

Starting with systemd-236, the sysv-utils USE flag is enabled by
default. 

The sysv-utils USE flag controls installation of symlinks for several
key commands:

    /sbin/halt -> ../bin/systemctl
    /sbin/init -> ../lib/systemd/systemd
    /sbin/reboot -> ../bin/systemctl
    /sbin/poweroff -> ../bin/systemctl
    /sbin/runlevel -> ../bin/systemctl
    /sbin/shutdown -> ../bin/systemctl
    /sbin/telinit -> ../bin/systemctl

These commands are otherwise provided by sys-apps/sysvinit. This package
is blocked by systemd when the sysv-utils USE flag is enabled.

If you wish to keep sysvinit (and openrc) installed, you may disable the
sysv-utils USE flag locally.

If you run into unresolvable blockers with sysv-utils enabled, ensure
that you do not have any reverse dependencies of sys-apps/sysvinit
selected (in your world file).

Common packages to look for:

    sys-apps/sysvinit
    sys-apps/openrc
    net-misc/netifrc

The equery command from gentoolkit may help track down installed
packages that depend on openrc.

    equery depends sys-apps/openrc

+1

The news item reads very clearly to me. =:^)

Thanks especially for explicitly including the list of symlinks and that 
sysvinit otherwise provides those files, as well as the explicitly 
suggested equery depends line for those who need it.

You might want to mention that alternatively, uninstalling
openrc&sysvinit&netifrc on a systemd profile system is fine to do
these days, despite the warning.

Does this still cause a warning?  I thought that openrc/sysvinit were
now pulled in via a virtual these days (alongside systemd), and were
not directly in @system.  Or do we still have functions.sh issues?

Still throws warning due to unresolved bug https://bugs.gentoo.org/375115

If you're using netifrc's systemd support, this would break your
networking ;-).

I guess the winky face means you are not serious, but I'll respond anyway. :-)

I suspect the number of people using systemd with netifrc is in the
single digits. I would rather not clutter the news item to account for
this scenario.

I have added the following text after the third paragraph. Let me know
if this is insufficient.

Enabling sysv-utils should cause Portage to un-merge sysvinit and OpenRC
if they are currently installed. emerge may emit a warning message
before doing so; if you are booting with systemd, this message is safe
to ignore.

Just for the record,
 I'm using it if using systemd (desktop systems), it's the only network
manager that use iproute2 syntax, shortening it if context is available
(no need to specify interface if it's mentioned in variable name f.ex.).
Beside I don't like NetworkManager

worse than that I'm actually using the same gentoo image with openrc and
systemd in different scenarios.
Basically my build box is using openrc inside a lxc container (no use of
netifrc, since net is managed by lxc).
The clients of the build box instead boot with systemd _and_ netifrc.

Gentoo is used by people who like to change defaults and (ab)use the
(autodocumented) flexibility offered by portage and ebuilds. Don't be
light in assuming how strange people is using strange configuration, and
population of strange people, that could be surprising.

It was a GSOC project, but since then I hadn't heard of any users of it,
other than the GSOC student, and haven't had any bug reports of it being
broken.

I'm happy to hear it has at least one other user in Francesco.
