That's not true. If you can script it, FAI can do it. It just becomes a
post-installation task. Using packages.d.o as an example, it's just going to
be a predominantly an Apache configuration and some scripts, right? So you
restore the scripts from backup, and dump the Apache config into the
appropriate directory, all from within FAI.

FAI can be a total disaster recovery solution when you couple it with your
backups, however I will freely admit that it takes a lot of time (and
testing) to get it such that you can punch out an identical box,
sausage-machine style. Then of course you need to keep it up to date as

Excluding the developer accessible machines, of the boxes that provide
critical Debian infrastructure, how many architectures are used? I know FAI
does i386 and Sparc.

newraff is i386
gluck is i386
murphy is i386
master is i386
merkel is ia64 - I have no idea if FAI can play ball on ia64

But the majority of what I believe to be project-critical machines are on
i386, which FAI can help with the receovery of.
