# sys.logbootcomplete is a signal to enable the bootstat logging mechanism.
# This signaling is necessary to prevent logging boot metrics after a runtime
# restart (e.g., adb shell stop && adb shell start). /proc/uptime is not reset
# during a runtime restart, which leads to false boot time metrics being reported.
# The 'on boot' event occurs once per hard boot (device power on), which
# switches the flag on. If the device performs a runtime restart, the flag is
# switched off and cannot be switched on until the device hard boots again.
# Enable bootstat logging on boot.
