# sys.logbootcomplete is a signal to enable the bootstat logging mechanism.

# This signaling is necessary to prevent logging boot metrics after a soft

# reboot (e.g., adb shell stop && adb shell start).  /proc/uptime is not reset

# during a soft reboot, 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 soft reboot, the flag is

# switched off and cannot be switched on until the device hard boots again.

# Enable bootstat logging on boot.
