HP/UX kernel building

Kernel building on UX 10.x

1. cd /stand/build


2. Create a new system file from the running kernel.

   /usr/lbin/sysadm/system_prep -s /stand/build/system



3. Edit the kernel with the planned changes.

   vi /stand/build/system



4. Build the new kernel.

   /usr/sbin/mk_kernel -s /stand/build/system



5. Copy the old system and vmunix files so if anything goes wrong, the system can be booted from the old kernel.

   cp /stand/system /stand/system.prev
   cp /stand/build/system /stand/system
   cp /stand/vmunix /stand/vmunix.prev
   mv /stand/build/vmunix_test /stand/vmunix



6. Reboot the system from the new kernel.

   shutdown -r
