Problem

          I want to make a copy of a kernel under a special name, but I am
          unable to do so as the /stand filesystem is read-only. How can I
          work around this?

CAUSE:

          The /stand filesystem is mounted read-only to provide protection
          for Unix kernel and boot programs in the event of a system crash
          that might result in filesystem damage or corruption.

Solution

          Use the btmnt(ADM) command as follows:

              # btmnt -w
              # cp unix.special /stand
              # btmnt -r

          IMPORTANT

NOTE:

      It is not recommended that you leave /stand
          mounted read/write permanently, as a system crash that results
          in filesystem damage may leave your system incapable of booting.

NOTE:

          Any kernel that you want to be able to boot from should have a name
          of the format 'unix.XXXXXX', where '.XXXXXX' is whatever extension
          you would like the kernel to have.  The 'unix' part must appear
          first; for example, 'unix.newkernel', as opposed to 'newkernel.unix'.
