Should we remove our custom > patch that adds this behavior? I would argue that our current behaviour provides a more usable default (eg. running vim via sudo uses your own configuration so you don't have to maintain a copy of it in /root) and in the case of a machine with multiple sudo users, they all get to use their own configuration rather than a single configuration under /root. However, it does diverge from upstream and so for new users this creates a surprising situation if they are used to and expect the upstream behaviour - (see comments 6 and 7 in https://bugs.launchpad.net/ubuntu/+source/sudo/+bug/760140) - plus it seems we do not document this change in the man page and so we are creating even more surprises for our users. From a security point of view I do not see any advantage from either behaviour, so it is really more a usability question IMO. > > for reference and more details on downsides of our current sudo behavior, see: > https://bugs.launchpad.net/ubuntu/+source/sudo/+bug/1556302 > > Note that I have kind-of hijacked the bug, as I believe the issue is > larger than the python-based example in that bug. > > Also as I commented in that bug, I do not recommend changing the > behavior for existing releases.

I agree if this is changed we should not try and SRU it back. -- Ubuntu-devel-discuss mailing list Ubuntu-devel-discuss@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-devel-discuss

Thanks a lot! > > Best regards > Chenghao WANG As part of sunsetting obsolete ubuntu releases, they do get archived to old-releases, and both installation media and the apt archive are still available as a a final snapshot only. So one can still consume that, even from a modern amd64 Ubuntu release, for example: $ mk-sbuild lucid --arch=i386 --debootstrap-mirror=http://old-releases.ubuntu.com/ubuntu/ --debootstrap-keyring=/usr/share/keyrings/ubuntu-archive-removed-keys.gpg $ schroot -c lucid-i386 -u root $ apt-get install nfs-kernel-server (downloads and installs all the packages one needs) Enjoy, but do please upgrade to Ubuntu 18.04 LTS Bionic! -- Regards, Dimitri. -- Ubuntu-devel-discuss mailing list Ubuntu-devel-discuss@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-devel-discuss
