Yes, and the tarball contains the path names of the files.  When 
extracting the tarball, you could remove the binaries and replace them 
with a list of the names of the files that were removed.  Given that 
list finding the installed copies of the files is trivial.

Yes, but it wastes time installing them in the first place.

Yes, but why install old packages first only to have to turn right 
around and install their updates?  It's another waste of time.

How so?  The configuration used on the livecd might fail when you try to 
boot from the hard disk.  The configuration of a freshly installed 
package might need to be modified to work on the cd, but when you 
install to the hard drive, you want the freshly installed configuration.

I guess you could make a script to revert such configurations when doing 
the copy, but it seems like that would be harder to maintain than simply 
installing the packages like normal, and letting them configure 
themselves when unpacked, the way the installer does now.
