14.5 Loading the HP-UX Kernel

   

---

The default HP-UX kernel is /stand/vmunix , which is loaded into memory by the secondary loader hpux . After loading the kernel into memory, the control is transferred to it. The kernel then loads the device drivers and starts the swapper process. It then initiates a shell process to execute commands from /sbin/pre_init_rc . After executing these commands, the first process, /sbin/init , is started and control is transferred to this process.

Swapper Process

The swapper process has a process ID equal to 0. It manages memory for swapping in and out.

/sbin/pre_init_rc File

The most important command found in this file is fsck , which checks and repairs the root file system before any user starts using it.
