Bug#1008668: bug #1008668: tomcat9: logrotated is not able to truncate catalina.out

[Evren Yurtesen]

Hi,

I am not sure if anybody received my previous e-mails as I do not see them in the mailing list thread. :(

>  What is the problem with logrotate? It happily rotates files owned by anyone in Debian.

Because in Ubuntu rsyslog drops privileges to `syslog` user. Therefore, the log files generated by rsyslog are owned by the `syslog` user. But tomcat9 logrotate configuration forces logrotate to become `tomcat` user, during rotation. Rsyslog fails to truncate the catalina.out file which has read/write permissions only for `syslog` user.

One solution would be undoing https://bugs.launchpad.net/ubuntu/+source/rsyslog/+bug/388608 at Ubuntu. But I do not know how to reach to correct people at Ubuntu side. I also do not think I could convince them that this is creating problems.

It is really sad to see that a simple problem related to a single file's permissions can take so long to resolve. Any help you can provide is welcome. 

Thanks,
Evren
