Bug 896038 – net-misc/frr-8.4.1: log file is empty after logrotate

• Status: UNCONFIRMED
• Product: Gentoo Linux

The current version (net-misc/frr-8.4.1) and previous ones (8.2.2 and 8.1-r1) have the same issue: the /var/log/frr/frr.log file is empty after the first logrotate.

Here is the relevant snippet from /etc/logrotate.d/frr:

/var/log/frr/frr.log {
    su frr frr
    notifempty
    missingok
    postrotate
        /bin/kill -HUP `cat /var/run/*syslog*.pid 2> /dev/null` 2> /dev/null || true
    endscript
}

cat /var/run/*syslog*.pid returns "No such file or directory"
