[gentoo-user] "systemd sysv-utils blocker resolution"

[gentoo-user] "systemd sysv-utils blocker resolution"

[allan gottlieb]

I have a question on this news item.

I use systemd (gnome3) on a gentoo stable system.
eix reports that sys-apps/systemd-236-r5 is installed

But
   euse -I sysv-utils
reports
   no matching entries found

Is something wrong?

I do *not* have
  sys-apps/sysvinit, sys-apps/openrc, or net-misc/netifrc
in my world file.

However, the last two are installed.

thanks,
allan

Interesting.  Does /sbin/reboot exist?  What does "qfile /sbin/reboot" return?

The only thing that is changing is a default - that flag was defaulted
off before, and is defaulted on now.  So, an emerge --changed-use -u
world should reinstall systemd with this flag enabled, assuming you
didn't manually disable it.

In any case, you can probably actually survive without poweroff,
reboot, etc, assuming you shutdown using systemctl.  Obviously some
legacy scripts/programs/etc that are supposed to shut down your system
might balk at the missing symlinks.  All the use flag does is install
compatibility symlinks to systemctl for these sysvinit programs and
their manpages.

Unless you have some package installed that explicitly depends on
sysvinit or openrc you should be fine.  Do you actually get any
blockers/etc?

Ultimately it comes down to whether you care about the compatibility
symlinks.  It probably isn't a bad idea to have them though.  Maybe
some day you'll install a UPS and its shutdown scripts will just call
shutdown/poweroff/etc and not work.  Software that shuts down using
either systemctl or dbus would be fine.

I have not dis- or en- abled the flag

My poweroff sequence is to use the gnome icon to logoff
and then the gnome icon to poweroff

No blockers.  I have two similar machines.  Only problems are a
long-standing difficulty with one machine compiling chromium and a known
bug in compiling webkit-gtk-2.4.11-r200 on either machine.

Since you lean toward having the symlinks, why is the new default for
the use flag on?  Upstream?

Also why do I have the symlinks with the 236-r5 system, contracting the
news item.  (This is true for both machines.)

Thanks again for all your help,

Ok, your systemd is built with USE=sysv-utils.

When the flag is on the symlinks are created.  They're only missing
(from systemd) when the flag is off.

You have them because the default is USE=sysv-utils, which installs
the symlinks.

The real question is why euse didn't show you has having the flag
enabled.  That I'm not sure about.  It shows it as enabled on my
system.  I'd have to dig into where it is getting its data and how
this might get out of sync.

To avoid a second email - a lack of depcleaning might explain why
software like openrc/netifrc is still installed.  I don't believe it
has anything to do with the output of euse.

When you ran:

   emerge -auDN --changed-deps --with-bdeps=y @world

did you forget to run:

   emerge -a --depclean

afterwards?

I am indeed behind in depcleaning.  Does that explain why
   euse doesn't fine sysv-utils
and why
   I have the symlinks /sbin/poweroff and friends with systemd-236?

I will be working on depcleans but rather slowly.

thanks for the help.

Yes. How else is sys-apps/sysvinit going to be unmerged? Either you let 
portage clean it up (depclean), or you need to do it manually.

He already has sysvinit unmerged.  Portage unmerged that because it
was a blocker for systemd[sysv-utils].  Portage doesn't remove
non-blocking packages unless you run emerge --depclean.

I would use 'equery d openrc netifrc'to see what if anything depends on
them.  If you get packages listed, then you know why they are there, and
maybe why as well.  If it lists nothing, then --depclean should clean it
up when you get a chance to run it. 

Just my thinking.
