Red Hat Bugzilla – Bug 1350450
Last modified: 2017-08-15 04:37:39 EDT
Description of problem:
BZ1116999 moved creation of the symlink /etc/resolv.conf from tmpfiles to systemd-resolved runtime to avoid treading on NM's toes (0999-resolved-create-etc-resolv.conf-symlink-at-runtime.patch).
Fedora 24 now runs systemd-resolved with ProtectSystem=full.
This means that the service CANNOT create the symlink since /etc will be mounted read-only.
Version-Release number of selected component (if applicable):
I do not use NM. Used systemd-networkd since F22.
Changing to ProtectSystem=true side-steps the issue but defeats the added security.
The symlink needs to be manage by some other mechanism than a long-running service. systemd-networkd could be packaged as an alternative to NM and initscripts networking, with the symlink set on install. Could alternatives(8) handle it?
Move symlink creation to ExecStartPre?
The use of ProtectSystem=full in F24 may uncover similar issues elsewhere (mounton AVC?).
This message is a reminder that Fedora 24 is nearing its end of life.
Approximately 2 (two) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 24. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora 'version'
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version.
Thank you for reporting this issue and we are sorry that we were not
able to fix it before Fedora 24 is end of life. If you would still like
to see this bug fixed and are able to reproduce it against a later version
of Fedora, you are encouraged change the 'version' to a later Fedora
version prior this bug is closed as described in the policy above.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
I'm not even sure what the state is here. I'll reassign to rawhide so this doesn't get lost.
This bug appears to have been reported against 'rawhide' during the Fedora 27 development cycle.
Changing version to '27'.
