tldr: Ubuntu 24.04 rsyslogd apparmor profile denies /var/lib/rsyslog, so imjournal cannot save its cursor.
Problem
On Ubuntu 24.04 the shipped
rsyslogdAppArmor profile (enforce) only allows/var/spool/rsyslog/**, butprofile::logging::rsyslogpoints the imjournalStateFileat/var/lib/rsyslog/imjournal.state. Every write is denied (apparmor="DENIED" operation="mknod" name="/var/lib/rsyslog/imjournal.state.tmp" fsuid=0), so imjournal never saves its cursor and replays from a stale position on each rsyslog start.Changes
This adds
/etc/apparmor.d/rsyslog.d/linuxaid-imjournalon Ubuntu with read on the directory andrwkon its contents. The profile already doesinclude if exists <rsyslog.d>, and the rsyslog unit reloads the profile inExecStartPre, so the file notifiesService['rsyslog'].
