The default for logFile is /var/log/couchdb.log, and the tmpfile rules chown
${dirOf cfg.logFile}, which is just /var/log, to couchdb:couchdb.
This was found by Edes' report on IRC, which looked like
Detected unsafe path transition /var/log → /var/log/journal during canonicalization of /var/log/journal
While this bug has been present since the initial couchdb module in
62438c09f7cc811f994510550614c9265b3b1d18 by @garbas, this wasn't a
problem, because the initial module only created and chowned /var/log
if it didn't exist yet, which can't occur because this gets created in
the initial phases of NixOS startup.
However with the recent move from manual preStart chown scripts to
systemd.tmpfiles.rules in 062efe018d571b1daa9c37b8c99eb39ad47d7342 (#59389),
this chown is suddenly running unconditionally at every system
activation, therefore triggering the above error.
Nixpkgs is a collection of packages for the Nix package manager. It is periodically built and tested by the Hydra build daemon as so-called channels. To get channel information via git, add nixpkgs-channels as a remote:
% git remote add channels https://github.com/NixOS/nixpkgs-channels.git
For stability and maximum binary package support, it is recommended to maintain
custom changes on top of one of the channels, e.g. nixos-19.03 for the latest
release and nixos-unstable for the latest successful build of master:
% git remote update channels
% git rebase channels/nixos-19.03
For pull requests, please rebase onto nixpkgs master.
NixOS Linux distribution source code is located inside
nixos/ folder.
