[TriLUG] Ubuntu reinstall and copying over /home

[Matthew Glassman via TriLUG]

Okay I tarballed my /home directory as a gzip file onto an external drive. It was not its own partition. I reinstalled Ubuntu and made /home it’s own partition this time in the setup.  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.

Regards,
Matthew
