How to reinstall without changing anything?
A couple of times I've gotten nervous about whether I could have been hacked,
back before I got a good iptables set up and turned off sshd etc. I've run
various diagnostic scripts but generally found them to be overly prone to
false positives. My *guess* is that I'm fine, given that no one's made any
charges to my credit cards and no one's complained that my machine is being
used to attack others.
Still, if there were a simple way to reinstall, keeping all the same
packages and not losing any customizations, I might do it. But I don't
recall any way to avoid answering a million questions at install time.
Really, I shouldn't have to answer *any* -- I want all the same packages,
same /etc/fstab, same rcconf configuration, same cups configuration, etc etc etc.
So is there any way to do a sarge installation while keeping all the
same stuff, not having to go through all the tiresome interactive questionnaires,
and (preferably) with iptables enabled, so that no one can hack in
during the install itself?
