If the new kernel is built successfully, the system saves the original kernel in /stand/unix.old if possible. Then, it copies the newly built kernel to /stand/unix. If the copy fails, the system tries the copy again after removing the saved old kernel. If the copy fails again, you are prompted to remove some files from /stand to make room for the new kernel.
To enable the installation of a new kernel after a failure, respond to the prompt to remove files by pressing <ENTER>.
You see the following:
Please enter the file(s) to be removed: unix.save1 unix.save2
Installed new UnixWare Operating System kernel.
You can name more than one file. The files you specify are removed, and the system tries to copy the kernel again. If the copy still fails, this scenario is repeated until the kernel is successfully installed or until you press <Esc> at the confirmation prompt.
