# 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.
