|Summary||0005119: followup to 0005078 / GNS library file changes|
|Description||I was just informed that https://gnunet.org/bugs/view.php?id=5078 was solved by:|
> Users / distros now must manually move the $PREFIX/lib/gnunet/nss/* files to the respective directory where libc expects NSS plugins (or adjust the search path).
This is bad in practice. There is no notice about this, no message. And even if you are expected to read something as a package maintainer (as in package in distro) you are likely to miss it.
The best is to to assume no interaction.
So what's the best way to solve this? I can simply adjust this on my system and the package, that's not a problem.
There should be a configure time option to select the directory for this.
|Tags||No tags attached.|
||The big issue here is that this is not so much about installing the plugin in the NSS directory. The bigger required change (for the user) is to activate it by editing /etc/nsswitch.conf. Doing that is a big decision, so it should only be done by a package maintainer or end-user who knows what they are doing (and how to revert).|
/etc/nssswitch.conf is no problem in my opinion.
What bothers me more is expected manual intervention for lib/gnunet/nss/* ... the nssswitch.conf can be installed (it is now in contrib/conf/nss/) as "example" data under share/gnunet/nss/$file.
It's not problem to adjust and extend the nss search-path, but we should communicate it. 9 out of 10 package maintainers will probably not get it if we simply write it in the manual. And for those who skip the README file, we can make an output on the screen ("for nss support, do...") after make has finished.
That's how I would resolve this issue for now.
||Having a configure option still means maintainers could miss it. But feel free to add it, as long as not setting it doesn't break the build.|
||Another take on this: install it as example data as part of a normal installation.|
||You mean the configuration file? I hope you don't intend to install the plugin as example data ;-)|
Yes, the configuration file.
Since it's been a while, can you list the files required for this to be copied, including the configuration file?
in the default setting, $out/lib/gnunet/nss/ does not exist, so I have no current list to go by (or I failed to pass the path to nss).
Basically, the line "hosts" in /etc/nsswitch.conf must be changed
to contain gns.
hosts: files mdns4_minimal [NOTFOUND=return] dns mdns4
hosts: files gns [NOTFOUND=return] mdns4_minimal [NOTFOUND=return] dns mdns4
No other files are involved, no .so moving somewhere by hand / automation?
||Only this file, plus that the NSS plugin must be in the "correct" location.|
Okay, I think I can work with this.
This could be closed for now, we should work this into the README, the documentation handbook and other relevant parts as well as include it as a change in the release message maybe (for maintainers to pick up on it).
Ok, for the release message, I've started a pad for collaborative editing:
