2 - Replace the old script with the new one.
You can delete first the old file with
rm /etc/rc.d linux
then open a text editor, copypaste the script and save the new file as linux.
ee /etc/rc.d linux
Or you can open the old file with a text editor, copypaste the new script over the old, and overwrite the original file.
3 - Edit these lines in the script:
Line 11:
name="linux"
Line 13:
rcvar="linux_enable"
Then save (or overwrite) the file.
