Subject: [PATCH] Avoid forever loop for journalctl --list-boots command
a19bc6
 (#4278)
a19bc6
a19bc6
When date is changed in system to future and normal user logs to new
a19bc6
journal file, and then date is changed back to present time, the
a19bc6
"journalctl --list-boot" command goes to forever loop. This commit tries
a19bc6
to fix this problem by checking first the boot id list if the found boot
a19bc6
id was already in that list. If it is found, then stopping the boot id
a19bc6
find loop.
