New systemd dependencies

Question

It looks like something has created a new systemd dependency.  I run an XFCE4 desktop and explicitly want to avoid systemd but as of the latest portage update emerge is wanting to pull in udev and systemd.   I'm still learning my way around  portage so I haven't figured out yet exactly what has changed to create this requirement.  I haven't changed any USE flags recently.


$ sudo emerge --ask --update --newuse --deep --with-bdeps=y @world

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

!!! Multiple package instances within a single package slot have been pulled
!!! into the dependency graph, resulting in a slot conflict:

It may be possible to solve this problem by using package.mask to
prevent one of those packages from being selected. However, it is also
possible that conflicting dependencies exist such that they are
impossible to satisfy simultaneously.  If such a conflict exists in
the dependencies of two different packages, then those packages can
not be installed simultaneously. You may want to try a larger value of
the --backtrack option, such as --backtrack=30, in order to see if
that will solve this conflict automatically.

For more information, see MASKED PACKAGES section in the emerge man
page or refer to the Gentoo Handbook.

NOTE: The --autounmask-keep-masks option will prevent emerge
      from creating package.unmask or ** keyword changes.

Use --autounmask-write to write changes to config files (honoring
CONFIG_PROTECT). Carefully examine the list of proposed changes,
paying special attention to mask or keyword changes that may expose
experimental or unstable packages.

it is already reported. This is issue is complex and it will take some time to resolve. Until then it is recommended not to let portage do updates. Nothing serious if box not updated for a couple of days.

 

Thanks.  Do you expect that clearing up the upower issue in FL-1261 will eliminate whatever dependancy is attempting to drag systemd into the mix?

 

Based on the news item in the latest update it's clear that systemd is once again the root of all evil.  Or at least this issue.  I wish I could be more helpful in isolating the issue but I'm new here and still learning portage.

No, systemd is not the root case of this issue but is a side effect of dependency choice dictate of virtual packages. Regarding udev, portage tree have 3 virtual packages:

 

virtual/udev (eudev, systemd, udev as providers).

 

Udev package has following libraries, libudev and libgudev (gudev part) and hence addtional virtual packages introduced:

 

virtual/libudev for packages linked against libudev (libudev can be provided either by eudev, systemd or udev, see above virtual/udev)

 

virtual/libgudev for package that linked against libgudev (same providers).

 

upower and upowr-pm-utils (drop-in replacement) now has virtual/libgudev dependency. Funtoo has no newer udev package, so virtual/libgudev dictates to choose systemd, eudev and other uncertain dependency graph. I find this behaviour as very misdesigned (or overly designed), which not helping Udev maintainence any better. I'm thinking about a permanent LONG-TERM fix for udev and Co. There was an initiative to use mdev as default but this is very conservative and better suited for servers, not desktops. Also, we would like to investigate possibility to switch to eudev, sa-called udev fork, which is freed from systemd churn, we had positive feedback from users, so it might be best option. The fix for this is ON HOLD as it one of the most critical packages in system.

P.S Funtoo has done good job in avoiding newer udev versions but number of problems accumulated dictates to have a permanent fix (if possible)

My reference to systemd was because systemd's consumption of more and more user space ultimately led to the changes in udev and upower that are now creating problems.

I was able to suss out a lot of the dependencies you talk about.  At least I'm learning a few things about portage in the process.  I don't mind that I can't update my home system but unfortunately this is also stopping me from completing the build on my new work system which is a bit more painful.  

 

I tried switching the build profile to stable (after I'd already emerged quite a few packages under "current") but it still hits the problem packages.  Would starting the build from scratch with the stable build profile fare any better?  It seems like with these issues lurking out there it would be desirable to make sure that "stable" always builds even if it doesn't get updated for a long time.

 

I understand what a sticky problem some of this is and I can't emphasize enough how appreciative I am that there are some developers who are willing to tackle these problems.  As much as some people want to push the need for uniformity in the Linux ecosystem I really believe that the ability to try different solutions and the "UNIX way" are much more important than just going along with the latest edict from the big contributors.
