to re-mount /stand read-write. After you have finished, use
to return it to its default state.
It would probably be a good idea to follow a procedure similar to this:
btmnt -w cd /stand cp unix unix.good cd btmnt -d
Unless, of course, "unix" is not known to be a good kernel. As you can have as many copies as will fit, and boot from any of them simply by typing their name at the "Boot:" prompt, it's not a bad idea to have at least one "unix.safe" or "unix.emergency".
Of course you can't fit very many if the /stand filesystem was created at its default size of 15MB. As disks got larger, I'd give /stand a 30MB or larger size just to allow room for other kernels.
This "btmnt" command was used primarily by the SCO kernel linking scripts to update the /stand (SCO's boot fs partition) with a new kernel. Why not just use mount commands? I don't know - maybe because was needed in enough places that they wanted easy syntax.
