Impressed to see very active and supportive members in this mailing list! I
am thankful to all who replied to my query.
@Artie: Do you think that going for bleeding edge kernel versions won't
break up security? I had a bad experience with such bleeding edge kernel in
server machines. For Desktop machines, I feel it okay. Just a bit of
apprehension to adopt new kernel for a server environment.
@Shane: I could not follow what you meant by 'the card sitting in RH box".
I would like to create an image offlineand then dd to CF. Is there any
specific scripts to do so from a normal debian/ubuntu installation? Sorry
for my confusion.
