boot2 is the first non-built-in sysmodule. It's presumably hardcoded to be the first sysmodule launched by PM.

boot2 is the first non-built-in sysmodule. It's hardcoded to be the first sysmodule launched by PM.
   −
It connects to "pm:shell" service and launches the following titles in this order:
+
On retail systems, the boot2 title is called [[#boot2.prodBoot|boot2.prodBoot]] while on debug systems it's called [[#boot2|boot2]]. Debug systems also have a version called [[#boot2.SafeMode|boot2.SafeMode]] installed in SAFE for safe mode. During [[Factory Setup|the factory setup process]] the boot2 title is called [[#boot2.manuBoot|boot2.manuBoot]] instead.

It opens the [[Process_Manager_services#pm:shell|pm:shell]] service and prior to [[10.0.0|10.0.0]] launches the following titles in order:

Then it connects to "set:sys" and reads a bool from "boot" section called "force_maintenance" with default value true.
+
It then opens the [[Settings_services#set:sys|set:sys]] service and reads a bool from the "boot" section called "force_maintenance" with default value set to "true".
   −
If the value reads successfully as false, it initializes "gpio" and opens sessions for GPIOs 26 and 25.
+
If the value reads successfully as "false", it opens the [[Bus_services#gpio|gpio]] service and opens sessions for GPIOs 26 and 25.
−
If both GPIOs read as zero, then maintenance mode is forced. This probably checks if both volume up and down keys are held down at the same time?
+
If both GPIOs read as zero, then [[Recovery_Mode|maintenance mode]] is forced despite the setting being false. This checks if both volume up and down keys are held down at the same time.
   −
Then depending on maintenance mode or not it launches the following titles in this order:
+
If it's in maintenance mode then it opens the [[Process_Manager_services#pm:bm|pm:bm]] service and calls [[Process_Manager_services#pm:bm|SetMaintenanceBoot]].
