Hi all,
My name is Jacob and I'm new in this group.
I agree with keean's idea about some kind of save and restore. For me, it's not
so much about tweaking at boot time (I agree that should be done by the
distribution), but rather for testing and evaluation and to be able to test
multiple settings in scripts.
All the best, Jacob
