[TriLUG] Ubuntu reinstall and copying over /home

[via TriLUG]

Yeah, if you want to kill your system. Ubuntu wires a new /etc during installation. It reflects partitioning in fstab.  You said you had a separate partition for /home. It may well point to a different UUID. It could take a year to fix that alone. Play it safe and let the ubuntu installer do its thing. Then copy DATA files. Edit newly created dot files that you previously customized. I have never copied over /opt, etc., during a new install. 

Another example: if a program is updated to a need version during a new install, three of .config might be wrong for it.

Good luck.

How about /etc  or /usr ?

Can someone guide me through how I should move the tarball file back to the new install as my /home ?  I also copied my sources.list file for apt and a few other directories like /opt /usr if it would be good to put those back on.
