This is a follow on question from the thread before.
I want to copy a file (grub.0 or grub.1) into grub.conf upon using
Grub. The object of this is to change the subsequent grub.conf to the
file that contains the default choice that is a match for the choice
chosen. Example: if grub.0 contains the default=0 line and this
corresponds to Linux, when I chose Linux I want this file copied to
Grub.conf. And when I chose DOS I want the grub.1 file containing the
line default=1 (and other lines of the grub.conf file) to be copied
over the Grub.conf file. As I said in the other thread, if this was
DOS and autoexec.bat/config.sys, this would be a way to do this.
Likewise, if a direct copy can not be done, doing a script or shell
command file may be able to be done. The major problem I would face is
that there is not a shell at the time that Grub runs.
