Re: LVM on debian

Hi all!

Maybe a bit too Debian-specific :-)

Filling /etc/default/grub with all the variables empty by default (or
commented, as other files in the same dir, e.g. ifupdown) is for sure an
improvement over the current situation.

This would work for upgrades grub -> grub2, but not for existing
installations (see Debian bug #459247 [1]).  So, yes, this can be done,
but having proper documentation (hint, `man update-grub`) would be the
best thing to do.  What's funny is that I had on my ToDo list a note to
submit a Debian bug about the same issue ;-)

Thx, bye,
