FAQs:
———–
Q: On which disk should I install my operating system?
A: You should try to install your operating system on one internal disk. If you spread you OS on to more than one disk, you have increased the opportunity for disk failure. For example, if you spread your OS across two disks, you now have two opportunities for a disk to fail instead of only one. Losing any one disk could take out the OS. Use one disk. And if availability is critical, then mirror the root volume group. More on this later. The actual disk name is not important. So, whether hdisk0 or hdisk1 is used doesn’t matter as long as the one you pick is an internal disks.
?????
Q: What does “cultural convention” mean in the installation process?
A: Cultural convention refers to things like date formatting and monetary symbols. For example, European languages will present dates in day/month/year format whereas US English will use month/day/year formatting.

Q: When my classical machine is installing the operating system, what happens if I forget to change the key position to normal?
A: If the key position remains in service, the machine will boot from the installation media again.
