This bothers me too as a developer. I have created and maintain small
python program. The program itself requires almost no maintenance and
as far as I remember it has been compatible with any Python 3 version
since 3.2. The only thing that needs constant maintenance is the ebuild
where a list of exact Python versions have to be updated with each new
major Python release:
PYTHON_COMPAT=( python3_{6..9} )
It is not even possible to "outsmart" it with 'python3_{6..255}' or
something similar to be future proof.
I do not know the reasoning for such handling of Python in Gentoo.
Maybe I am oversimplifying it but I'd expect that specifying
dependencies to Python will be simple as any other. Something like:
RDEPEND=">=dev-lang/python:3"
Why this is not the standard and recommended way?

Hi, man 5 ebuild tells us that: = Indicates that any slot value is acceptable. In addition, for runtime dependencies, indicates that the package will break unless a matching package with slot and sub-slot equal to the slot and sub-slot of the best installed version at the time the package was installed is available. In this it case means that inkscape wants the same slot version of imagemagick as it was present in the system at the time inkscape got emerged. So if you update imagemagick to a higher slot, inkscape will break and needs to be rebuilt. The rebuild should have been automatically scheduled by emerge. I am not sure why it did not but you have probably too many other conflicts and emerge got lost in that mess. ;-) It usually helps if you make all the USE flag and keyword changes that emerge wants you to do first. If it does not help then unmerge inkscape and emerge it again after update. > after switching this cxx-thingy off and on again, I get additional > errors: > > dev-python/numpy:0 > > (dev-python/numpy-1.17.4:0/0::gentoo, ebuild scheduled for merge) > conflicts with > dev-python/numpy[python_targets_python2_7(-),python_targets_python3_6(-),-python_single_target_python2_7(-),-python_single_target_python3_5(-),-python_single_target_python3_6(-),-python_single_target_python3_7(-)] > required by (media-libs/opencv-4.1.2:0/4.1.2::gentoo, installed) This looks like python is going to be updated.

The emerge should print/log which kernel options you do not have and
should have enabled if I am not mistaken. Docker uses some advanced
kernel features. I forgot to mention to check the kernel config in
my quick start, sorry.

Add yourself to docker group; re-login 3. Choose docker image that you like on hub.docker.com; for example: https://hub.docker.com/r/openhs/firefox-ubuntu/ as I have mentioned in previous mail. It's what I've made for myself and published. 4. Follow instructions for your chosen image how to run it. For the openhs/firefox-ubuntu image above, the following command should start Firefox: $ docker run --name firefox -e DISPLAY=$DISPLAY --device /dev/snd \ -v /tmp/.X11-unix:/tmp/.X11-unix \ -v $XAUTHORITY:/tmp/.host_Xauthority:ro -dti openhs/firefox-ubuntu What it does is: from image openhs/firefox-ubuntu it creates container named 'firefox' and starts it. (The image is downloaded automatically.) This long command is needed only for the first time. Next time you can start it with: $ docker start firefox Some basic docker commands: $ docker ps [-a] - lists running containers [or all containers] $ docker images - lists images $ docker rm [container_name] - removes container $ docker rmi [image_name] - removes image The official documentation is pretty good: https://docs.docker.com/get-started/ Regards, Robert -- Róbert Čerňanský E-mail: ope...@tightmail.com Jabber: h...@jabber.sk

I've > recently started using "--with-bdeps=y" as well, and I don't think > I've seen this happen since then, so I'm guessing binary deps are the > culprit. I think so too. Since Dan does not use --with-bdeps this is what might happen: 'qtdeclarative', 'qtxml' and 'qtcore' were updated from 5.6.1 to a higher version. However 'linguist-tools', being only a build dependency, was not updated and remains at version 5.6.1. Since 'linguist-tools-5.6.1' depends on 'qtdeclarative-5.6.1', 'qtxml-5.6.1' and 'qtcore-5.6.1' --depclean resolves those as missing packages. So as Arve is saying - using --with-bdeps should prevent this. There are two ways how to use it: - As 'emerge -uDN --with-bdeps=y world' - in this case build dependencies will be updated as well. - As 'emerge -ac --with-bdeps=n' - in this case build dependencies will be depcleaned (removed). Notice there is 'n' in --with-bdeps. I prefer second option since this leaves a clean system where only packages required to run it are installed. Disadvantage is that upon next update the build dependencies are emerged again, so it takes more time to update the system.

[gentoo-user] Managing network interface in a namespace
Hi all,
I would like to bring up and configure a network interface which
exists in a (network) namespace. I would like to use standard OpenRC
'net.' init script to do so.
Since the interface (veth1) exists only in a namespace (myns) I need
that the init script would be executed within that namespace:
ip netns exec myns /etc/init.d/net.veth1 start|stop|...
While I can do that manually as above the automatic run (during boot)
is however executed in the global namespace.
My current, not very good approach is that I've created a wrapper around
runscript and created a copy of /etc/init.d/net.lo
to /etc/init.d/net.veth1 where I've changed the first line to that
wrapper. It does work when invoking the script manually but it is not
executed by OpenRC at all during boot or when I type 'rc' even if
net.veth1 is included in default runlevel. Also, to have a copy of init
script is not very nice. Therefore I'm seeking other solutions. Is
there any way to tell OpenRC that it should configure an interface
in a specific namespace?
The wrapper script for curious:
#!/bin/sh
namespace=${1}
shift
/bin/ip netns exec ${namespace} /sbin/runscript ${@}
First line of /etc/init.d/net.veth1 then looks like this:
#!/usr/local/bin/runscript-netns myns

If yes then Flacon (media-sound/flacon) can be used to split the file according a CUE file. It has also CDDB support (even though I don't remember using it and in fact it shows an error popup when I've tried it now) or you can edit metadata manually. If you prefer command line then media-sound/shntool contains command shnsplit: $ shnsplit -f .cue For more mature metadata editing I recommend media-sound/easytag. If you do not have the CUE file then Ardour (media-sound/ardour) can be used to create it. You would have to manually mark beginning of each track and then export. (It requires Jack server so it is not a lightweight solution but I like working with it.) Also good old media-sound/gramofile should be able split files automatically, but I have no experience with it. Robert -- Róbert Čerňanský E-mail: ope...@tightmail.com Jabber: h...@jabber.sk

Execute 'emerge -pv foo', if you do not like the changes then tweak USE settings in package.use. I would not feel any less in control if I could see changes that portage wants to do and could force my USE settings in package.use. Honestly, I tend to agree with this approach. Imagine if when you typed emerge kde-meta the emerge program told you that you need to add the following 400 lines to your package installation list. Then we create a install-list-cleanup program that looks at your world file and determines what stuff you have in your package installation list that aren't needed any longer. Very good analogy. Except that for current USE flag situation we do not and even can not provide such install-list-cleanup program. There is no way to tell whether an entry in package.use is a user choice or it is there just to satisfy some dependency. Therefore no program can tell if it can be cleaned or not. Which is another manifestation why current approach is fundamentally wrong. When it comes to what packages are installed the design is to have the user stick the stuff they really care about in the world file and let the PM figure out how to make it happen. You can override masks in config files, but the general intent is that you don't have to do this most of the time. Why not make USE flags work the same way? Why can't emerge steam figure out that half the system needs to be rebuilt with 32-bit support, and then later emerge --depclean steam figures out that half the system can be rebuilt without 32-bit support? You could still specify global or package.use settings when you have specific preferences, of course. However, you wouldn't have to do that just to satisfy dependencies unless there is a blocker that portage can't figure out itself. That is also analogous to what happens when virtuals today - sometimes you have to manually uninstall/install something to get portage past a block, and maybe that will be needed with USE flags too. I think we've just gotten into a mode where we automate user configuration instead of eliminating the need for it. -- Róbert Čerňanský E-mail: ope...@tightmail.com Jabber: h...@jabber.sk

[...] There is no good reason whatsoever why portage shouldn't be able to treat this like a transitive required USE flag requirement, percolating through all libs from the toplevel requirement's dependency tree. Correct, there is no good reason why portage *can't* do that. There is a very good reason why portage *won't* do that, it is not the gentoo way and it goes against gentoo's social contract. Portage does not override your choices, and it certainly does not allow one single ebuild to automagically change the behaviour of multiple other ebuilds. The correct way to bring about changes in behaviour is to add your global choices to make.conf (which is outside the control of the tree), or to add your explicit changes to package.* It depends what you see as a user choice. In my opinion by writing 'emerge skype' to the console the user clearly states his choice to install skype. If he actually cares what that would mean for his system he can use --pretend or --ask option together with --verbose and tweak USE flags if and only if he does not like it. So user has still full control over his system. Portage's default behaviour when confronted with incompatible settings has always been to detect them, and print the output to the console telling you what to do. Now, there is a helper function that you as We could declare USE settings e.g. in make.conf as overridable by automatic USE dependencies so portage would not see it as incompatible. On the other hand package.use could be non-overridable thus allowing the user to have control over portage choices. the system owner can enable if you trust portage and the tree to always make the correct decision - autounmask. You can run it with -p Big advantage of automatic deps over --autounmask is that auto deps would not mess with user configuration files in /etc. Changed USE flags would be stored internally by portage.

I'd be interested in hearing about alternatives, but I switched to cfg-update from dispatch-conf and such because it does automatic 3-way merging. It is pretty good about detecting stuff that you customized and auto-merging those lines as long as the upstream file doesn't change. If it does, then you get a 3-way merge in meld or another tool to do the merge. 95% of the time it just automerges all config file updates without any interaction. dispatch-conf does automatic 3-way merge too, I guess. At least it offers me pre-merged file (that I have modified) from time to time which I can just confirm (right there in the console). But somehow it does that less often than I think it could and most of the time offers me just diffs. Although it is not that bad since there is not much of them (it does lot of full automatic merges without even asking for confirmation), there are some files for which I get diffs over and over again. sshd_config is one of them, same as the OP.

[gentoo-user] Systemd as drop-in replacement for udev?
Hello all, I am currently updating my system and Portage wants to replace udev (204) with systemd (208). My question is (hopefully) simple: Can I use systemd as drop-in replacement for udev? In other words, can I pretend that systemd is udev and continue using OpenRC as with udev itself? I would then apply just udev 204 to 208 update instructions (http://wiki.gentoo.org/wiki/Udev/upgrade). I am using WindowMaker and systemd was pulled in by gnome-settings-daemon which in turn was pulled in by gdm. I would like to stick with gdm. Usually I feel pretty comfortable replacing one package with another if Portage wants so (e.g. because they block each other) but in this case I want to be extra careful. I did not find a clear answer to this. Usually people either migrate fully to systemd (replacing openrc) or stays with udev + openrc.
