Yes, that's an excellent start -- thanks! However, unless I'm even less clueful than usual, that needs some augmentation if someone should be reasonably expected to take that file & be able to reconstruct the machine on which the file was created (assuming, say, "dump" backup images for all filesystems). For example, information about disk partitioning would seem to be necessary, as well as interpreting the "dmesg" output so someone could determine what cards go in what slots (assuming it makes a difference?). Please recall that the intended purpose is to be able to reconstruct the environment, assuming that (for whatever reason(s)) access to the original machines is not available (either for poking & prodding or logging in). Of course, I'm certainly open to comments like "this isn't really feasible" -- but it seems to me that it's just part of normal disaster recovery preparedness... and I'd think that folks have addressed the issue in some form previously....
