While trying to restart services controlled by /etc/init.d/local on a VPS, I found that /etc/init.d/local itself was missing. I tried rc-status to see what was running...it said "command not found." WTF? I checked another system and found that /bin/rc-status on it belonged to sys-apps/openrc. Back to the VPS.../var/log/emerge.log says that openrc was removed two weeks ago.

I let emerge -1 openrc run to get things back where they should be. emerge --depclean then wants to remove it again.

I then ran emerge -e1av virtual/service-manager. It pulled in 100 different packages, including openrc. If I follow it with emerge --depclean, it wants to remove it again.

I could emerge openrc (without -1) to add it to the world set, but I shouldn't have to do that. None of my other Gentoo systems (all of which get updated about once a week) have had this problem. Why is this particular system intent on removing openrc?

Maybe this is a stupid question but are you running systemd on that install? I just had depclean propose to remove openrc on my systemd Gentoo install. Out of curiosity I went ahead and let it do it and rebooted. And here I am. Everything went fine. :)

So it appears systemd users may not always need openrc installed now. I know there was an open bug about removing the openrc requirement for systemd installs for some time. It is nice to see things finally resolved.

There was a news item about this from a couple of months ago, although portage just came up with this and associated dire warnings on my sync this am. The news is a bit thin, There's more information in this thread

Nope. One of the reasons (among others) that I've stayed with Gentoo is that it makes it easy to avoid that dumpster fire.

Something is off. You must have systemd (or another init system) installed. Remove it and openRC will be selected by default.

I recommend masking systemd because something must have pulled it.

8O I've only seen openrc --depcleaned on systemd desktops, and even then portage made a lot of noise about removing an @system package.

I haven't seen any attempt to --depclean openrc on an openrc system. There would be users chucking fits everywhere if this was a bug, so it's something on your system.

Sorry, I misread your initial post and assumed this was systemd related, the post I linked is useless for this issue.

equery list \* | grep systemd returns nothing, as I would expect. systemd is not on this box.

It's a good thing I didn't have to reboot this VPS while openrc was missing. Portage does bitch about how "openrc is part of your system profile," and equery depends openrc returns net-misc/netifrc and virtual/service-manager.

Looking at the virtual/service-manager ebuild, it appears it can be satisfied by not just openrc or systemd, but also runit and daemontools. I do have daemontools installed; it's pulled in by djbdns. I've had djbdns (and daemontools) on this VPS ever since I set it up however many years ago (first entry in emerge.log is datestamped 18 April 2014), but as near as I can tell, it looks like openrc was unmerged about two weeks ago. The last change to virtual/service-manager was back in February, so that isn't it.

I had djbdns installed because I was serving up DNS records for my domains, but I've migrated that service to DirectNIC. I've uninstalled djbdns. emerge -a --depclean now wants to remove daemontools and is finally leaving openrc alone. If I bring back djbdns and then emerge -a --depclean, it wants to remove net-misc/netifrc, sys-apps/openrc, sys-apps/sysvinit, virtual/tmpfiles, and sys-apps/opentmpfiles.

emerge --noreplace openrc

https://dev.gentoo.org/~zmedico/portage/doc/man/emerge.1.html

Because you have another manager the virtual deems openrc redundant. The above command will put openrc in the world file without re-emerging it or doing a risky edit.

I too am in the same boat now as @salfter: I have a kvm/QEMU host which is purely OPENRC with these installed packages:
Code:
sys-apps/openrc-0.34.11::gentoo
sys-apps/sysvinit-2.88-r9::gentoo


And 'depclean' now wants to remove:
Code:
!!! 'sys-apps/openrc' (virtual/service-manager) is part of your system profile.
!!! Unmerging it may be damaging to your system.


 sys-apps/openrc
    selected: 0.34.11
   protected: none
     omitted: none

 virtual/tmpfiles
    selected: 0
   protected: none
     omitted: none

 sys-apps/sysvinit

WTF?!?!?! I don't know what to do with VIRTUAL Paperweights, when all my KVM guests would be taken off-line :-O

This showed up after a downgrade from kernel-4.12.12 to 4.9.72-gentoo ("stable" changed, and this is a production system that I need to keep stable... 4.12.12 brought a few weeks of horrible head-scratching weirdness, but it was after profile-changes, GCC-changes, etc. making the introduction of funkiness hard to pin down. With all these changes, again on dozens of production servers, December was the month of pogo-servers being rebooted every few hours to effect new kernel-changes :cry: ).

Here's my fairly-short world file:
Code:

You don't have USE=prefix enabled, by chance?

Because the virtual/service-manager ebuild
Code:
   prefix? ( >=sys-apps/baselayout-prefix-2.2 )
   !prefix? (
      || (
      sys-apps/openrc
      kernel_linux? ( || (
         sys-apps/systemd
         sys-process/runit
         virtual/daemontools
   ) ) ) )

should make portage always prefer openrc over systemd. Did you already check that sys-apps/systemd is *not* installed? (the world is not enough)

Here are my three USE-flags, as they appear in make.conf:
Code:
USE="qemu xfs -X"


emerge --info shows all the USE-flags, besides the three I set:
Code:
USE="acl amd64 bzip2 crypt cxx hardened iconv ipv6 multilib ncurses nls nptl openmp pam pcre pie qemu readline seccomp ssl ssp unicode xattr xfs xtpax zlib"


And no, there is no systemd; I am 100% certain of that!!
Code:
# emerge -pv systemd

These are the packages that would be merged, in order:

Python is implicated.

Before:

Code:
# eselect python list
Available Python interpreters, in order of preference:
  [1]   python3.4
  [2]   python3.5 (fallback)
  [3]   python2.7 (fallback)


and with this configuration, depclean wants to remove OpenRC! I don't recall ever messing with this file before, but I may have (sometimes 'fail2ban' or 'denyhosts' get fussy and crash...?).

I made one single edit, by adding this line to the bottom of /etc/python-exec/python-exec.conf:
Code:
python2.7



After:

Code:
# eselect python list
Available Python interpreters, in order of preference:
  [1]   python3.4
  [2]   python2.7
  [3]   python3.5 (fallback)



VOILA! I now get rational behaviour from my system! 'depclean' is no longer harassing OpenRC!

just hit this and fixed by make python2.7 as preferred interpreter, is there anything wrong if I prefer 3.6?

what the hell is going on here I wonder ...

Recently also set up a Gentoo instance inside KVM . Very OpenRC, very no systemd. First time `emerge -ac` it wanted to remove openrc! `emerge --noreplace openrc` "fixed" it. (It also wants to remove nano, but that's fine by me!)

What is the output of emerge --pretend --verbose virtual/service-manager sys-apps/systemd sys-process/runit virtual/daemontools sys-apps/openrc on a system where emerge --pretend --verbose --depclean sys-apps/openrc offers to remove openrc?

That is strange. The only guess I can offer is that there is some algorithm in use that depends on receiving dictionary elements in a particular order, and the "bad" Python versions return the elements in an undefined order, while the "good" versions return the elements in a consistent order. I see that gordonp had what is now a very old version of Portage, but that post is more than a year ago, so it's not necessarily relevant anymore. For the system with the inconsistent results, what is the output of emerge --info?
