Em man systemd-journald
:
FILES
/etc/systemd/journald.conf
Configure systemd-journald behavior. See journald.conf(5).
/run/log/journal/machine-id/*.journal,
/run/log/journal/machine-id/*.journal~,
/var/log/journal/machine-id/*.journal,
/var/log/journal/machine-id/*.journal~
systemd-journald writes entries to files in
/run/log/journal/machine-id/ or /var/log/journal/machine-id/ with
the ".journal" suffix. If the daemon is stopped uncleanly, or if
the files are found to be corrupted, they are renamed using the
".journal~" suffix, and systemd-journald starts writing to a new
file. /run is used when /var/log/journal is not available, or when
Storage=volatile is set in the journald.conf(5) configuration file.
E como man journalctl
diz:
journalctl may be used to query the contents of the systemd(1) journal
as written by systemd-journald.service(8).
Esses registros são gerenciados pelo serviço systemd-journald
, portanto, um termo mais apropriado seria " journald
logs".
