I think this is indeed the best solution, nevertheless I do not know
how to implement such persistent rules.
On my Lenny box, there are persistent rules for the ethernet cards and the cds,
but not for the hard drive:
for the cds, symbolic links are added, and this does not work for the sd*;
on the contrary, the ethernet card are renamed:
can we write persistent for the sd* similar to the one for the ethernet cards ?

Thanks in advance,
