Correction for section "Steps to reproduce" 3. systemctl start dnscrypt-proxy.service |
logrotate.service is unable to run successfully due to permission error on log directory. This seems to due to a combination of configuration in the systemd service and the installed logrotate configuration file for dnscrypt-proxy. systemd unit contains: DynamicUser=yes This moves log files from /var/log/dnscrypt-proxy to /var/log/private/dnscrypt-proxy and /var/log/dnscrypt-proxy is made into a symlink. # ls -ld /var/log/private/ /var/log/private/dnscrypt-proxy/ /var/log/dnscrypt-proxy lrwxrwxrwx. 1 root root 22 Sep 12 15:52 /var/log/dnscrypt-proxy -> private/dnscrypt-proxy drwx------. 3 root root 4096 Sep 12 15:52 /var/log/private/ drwxr-xr-x. 2 dnscrypt-proxy dnscrypt-proxy 4096 Sep 12 15:50 /var/log/private/dnscrypt-proxy/ From dnscrypt-proxy.service logs after changing it: ... systemd[31996]: Found pre-existing public LogsDirectory= directory /var/log/dnscrypt-proxy, migrating to /var/log/private/dnscrypt-proxy. systemd[31996]: Apparently, service previously had DynamicUser= turned off, and has now turned it on. ... Logrotate seems to fail because in /etc/logrotate.d/dnscrypt-proxy the following is set: ... su dnscrypt-proxy dnscrypt-proxy ... When user dnscrypt-proxy tries to access /var/log/dnscrypt-proxy it attempts to traverse /var/log/private to reach /var/log/private/dnscrypt-proxy which causes permission denied. See actual results for error. Reproducible: Always Steps to Reproduce: 1. USE="-cron" emerge app-admin/logrotate 2. emerge net-dns/dnscrypt-proxy 3. systemctl start net-dns/dnscrypt-proxy 4. systemctl start logrotate.service Actual Results: logrotate[32017]: error: stat of /var/log/dnscrypt-proxy/*.log failed: Permission denied systemd[1]: logrotate.service: Main process exited, code=exited, status=1/FAILURE Expected Results: logrotate.service can start without any
