[gentoo-user] systemd as a Profile - practical or not?

[gentoo-user] systemd as a Profile - practical or not?

[Tanstaafl]

Hi all,

Ok, before I go and open up a bug requesting this...

I know there have to be a lot of people on this list who can answer 
this question...

Is making the use of systemd or not based on a selected Profile, as 
opposed to manually trying to do it via USE flags etc, a practical 
request, or not?

Meaning:

1. is it doable,

2. how hard (on a scale of 1/easy to 10/hard to impossible) would it
    be to do this, and

3. regardless of the difficulty in achieving it, how hard would it be
    (on a scale of 1 (easy) to 10 (hard to impossible)) to maintain in
    the long run?

I'm hoping that even if the answer to #2 above is 7+, if the answer to 
#3 is 'relatively easy' or better, then maybe it still stands a chance 
of getting done.

And incidentally, Canek, if I was a programmer, I'd be happy to 
volunteer to take it on, but alas I'm just a lowly user...

Thanks...

How is this different from the status quo? There are several systemd
profiles available that make use of the files
in /usr/portage/profiles/targets/systemd/ to make the proper package
settings for using systemd on gentoo. AFAIU, a user should only need to
switch the profile, install and configure systemd itself and configure
their bootloader to start using systemd.

Of course it is.

Well, doing it I think it's easy.

That's the pickle, isn't? Forget about how "hard" it is.

The problem, as I see it, is that this systemd profile is being pushed
by the people that *don't* want to use systemd, because they want it
restricted to a separated profile so their machines are not "tainted"
by systemd.

If it was the other way around (systemd users wanting a systemd
profile), there would be no problem, since they would happily do the
job. But as it is it makes no sense; if you want to maintain a systemd
profile, you need to *use* systemd to do the testing and supporting.
Are the people that don't want to use systemd, will use systemd to
test and support a profile so they don't need to use systemd? Really?

(And never mind that more and more packages in the stack will want to
use systemd's features, and some of them probably will not work, or
work with limited functionality, without said features. And a profile
is not going to change that.)

That being said, the GNOME team introduced a gnome/systemd profile
(and later the KDE team did the same). I've never saw the point in
doing that, but that's what they decided and is fine.

If the Gentoo developers that use and prefer systemd decide to create
a systemd profile, then it will (easily, I think) happen.

But it's the systemd users the ones you should convince to do it; not
anyone *not* using it or avoiding it.

The possibility exists, sure. You can talk to Michał and the other
members of the systemd project in Gentoo. If you convince them that it
is a good idea (and good for systemd, obviously), they will do it.

But anyone that wants to help this happen will need to use systemd to
support a systemd profile. That's simple logic.

I would, but I don't think is worth it. It's not an unreasonable idea,
but I think it will make thinks muddy when someone chooses the "not
systemd" profile, and they will discover that anyhow they need systemd
to run a lot of things.

And, I repeat, usually when someone pushes for an X profile, it's
because they want to use X. In this case you are asking for an X
profile so you don't need to even see X; it makes no sense, since the
X profiles needs the people maintaining it to use X.

Interesting! I guess it's been a while since I looked at the available 
profiles, because I don't remember seeing those:

  # eselect profile list
Available profile symlink targets:
   [1]   default/linux/amd64/13.0 *
   [2]   default/linux/amd64/13.0/selinux
   [3]   default/linux/amd64/13.0/desktop
   [4]   default/linux/amd64/13.0/desktop/gnome
   [5]   default/linux/amd64/13.0/desktop/gnome/systemd
   [6]   default/linux/amd64/13.0/desktop/kde
   [7]   default/linux/amd64/13.0/desktop/kde/systemd
   [8]   default/linux/amd64/13.0/developer
   [9]   default/linux/amd64/13.0/no-multilib
   [10]  default/linux/amd64/13.0/x32
   [11]  hardened/linux/amd64
   [12]  hardened/linux/amd64/selinux
   [13]  hardened/linux/amd64/no-multilib
   [14]  hardened/linux/amd64/no-multilib/selinux
   [15]  hardened/linux/amd64/x32
   [16]  hardened/linux/uclibc/amd64

So, does this mean we will eventually have systemd choices for *all*? Ie:

  # eselect profile list
Available profile symlink targets:
   [1]   default/linux/amd64/13.0 *
   [1]   default/linux/amd64/13.0/systemd
   [2]   default/linux/amd64/13.0/selinux
   [1]   default/linux/amd64/13.0/selinux/systemd

etc?

I don't think this is difficult. I've been using gnome/systemd since > 1
month & I have a Gentoo server which uses systemd as well.

Burst out laughing reading this mail after reading this thread and the
other systemd one.
 Anyways you'll find instructions here http://www.gentoo.org/main/en/lists.xml.

Have a look at the files in profiles/targets/systemd/

http://sources.gentoo.org/cgi-bin/viewvc.cgi/gentoo-x86/profiles/targets/systemd/

That's all that is different in the systemd subprofiles. Easy to do manually.

Didn't we discuss this very question a few months back? (it might have
been on -dev though)

I recall a distinct sticking point being the immediate doubling of
number of profiles - you'd need as many as there are no, doubled. 1 for
a systemd version, 1 for a non-systemd version
