# There may be huge amount of pending messages in sockets. Processing them may cause journal rotation.
# If the journal is rotated in the loop below, some journal file may not be loaded and an unexpected
# result may be provided. To mitigate such, flush (if not yet) and sync before reading journals.
# Workaround for #32890.

# May 21 02:25:55 TEST-09-REBOOT.sh[433]: + journalctl --list-boots -o json
# May 21 02:25:55 journalctl[433]: Journal file /var/log/journal/173da2fad3064e3e9211a7ed7d59360b/system.journal is truncated, ignoring file.
# ===
# If that happens, the entries stored in the journal file are ignored, and the results of --list-boots
# and subsequent call of journalctl may become inconsistent. To prevent such issue, let's also rotate
# the journal. Then, all journal entries we are interested in are stored in the archived journal files.
