Ok, thinking about it for a moment, I can't actually think of a way how this could have any adverse effects. rsyslog is anyway a very privileged thing (just by checking the capabilities), so adding it to tty should not really have any effect (as it already is meant to have rw access to tty's). Maybe I'm missing something here, but so far this feels safe.
As for the SRUability of that, I think this does count as a bugfix so in theory should be SRU material. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to rsyslog in Ubuntu. https://bugs.launchpad.net/bugs/1890177 Title: rsyslogd: file '/dev/console': open error: Permission denied Status in rsyslog package in Ubuntu: New Status in rsyslog source package in Focal: New Bug description: The Privilege Drop options ($PrivDrop*) in focal's rsyslog both point to 'syslog' for the user and group, and don't match the ownership/permission of '/dev/console' generating the following: syslog:Aug 3 15:16:58 <HOSTNAME> rsyslogd: file '/dev/console': open error: Permission denied [v8.2001.0 try https://www.rsyslog.com/e/2433 ] Looking in Bionic/18.04LTS, '/dev/console' used to be root:syslog[1], nowadays it's root:tty[2] [1] - Bionic/18.04LTS (Gcloud instance) # ls -l /dev/console crw--w---- 1 root syslog 5, 1 Aug 3 15:17 /dev/console [2] - Focal/20.04LTS (Gcloud instance) # ls -l /dev/console crw--w---- 1 root tty 5, 1 Aug 3 17:19 /dev/console # /etc/rsyslog.conf $PrivDropToUser syslog $PrivDropToGroup syslog ** As a debug exercise I did the following: - Cannot reproduce the situation if I intentionally get rid of the PrivDrop* options. - Cannot reproduce the situation if I intentionally add 'syslog' user member of 'tty' group. Meaning that it's pretty obvious with the above statement that the permission denied is caused by the permission/ownership mismatch between '/dev/console' 's ownership permission & syslog user (PrivDropTo[User|Group]).
