Eu consegui que isso mudasse a propriedade de messagebus.adm
para syslog.adm
e, em seguida, reiniciei o rsyslog.
Meio perturbador que isso quebrou silenciosamente. Dada essa experiência, não estou muito confiante de que os outros arquivos de log sejam de propriedade correta. Aqui está o que tenho atualmente:
-rw-r--r-- 1 root root 0 May 1 06:31 alternatives.log

Isso parece correto?
