in grub.cfg: how to initialze a variable from the contents of a file

[Dr. Zimmermann]

Hi,

a general question concerning variable initialization in grub.cfg:

As the subject says I'd like to initialize a variable in grub.cfg 
(dynamically during runtime) from the contents of a file.

In a shell, I'd simply do something like:

        myvar=`cat myfile`;

As far as I'm aware there aren't any exec quotes `` in the grub shell. 
Instead, at least the search command has a '--set' option to pass the 
return-string to a variable.

I haven't found such a mechanism for the 'cat' command. Also, setting 
the variable via redirection and file inclusion seems not possible.

Are there any way to solve the problem?
