The exact action to be taken is determined by the +flags passed in +.Fa howto +and by whether or not the system has finished autoconfiguration. +.Pp +If the system has finished autoconfiguration, +.Fn boot +does the following: +.Bl -enum -offset indent +.It +If this is the first invocation of +.Fn boot +and the +.Dv RB_NOSYNC +flag is not set in +.Fa howto , +syncs and unmounts the system disks by calling +.Xr vfs_unmountall 9 . +.It +Disables interrupts. +.It +If rebooting after a crash (i.e. if +.Dv RB_DUMP +is set in +.Fa howto , +but +.Dv RB_HALT +is not), saves a system crash dump. +.It +Runs any shutdown hooks previously set by +.Xr at_shutdown 9 . +.It +Prints a message indicating that the system is about to be halted +or rebooted. +.It +If +.Dv RB_HALT +is set in +.Fa howto , +halts the system. +Otherwise, reboots the system. +.El +.Pp +If the system has not finished autoconfiguration, +.Fn boot +runs any shutdown hooks previously set by +.Xr at_shutdown 9 , +prints a message, and halts the system. +.Pp +.Sh SEE ALSO +.Xr at_shutdown 9 , +.Xr vfs_unmountall 9
