Apologies for the double post... I have noticed in other forums that an edit usually won't flag a thread with "new posts".
I do like the idea of remastersys, but after testing a few of the different repository links, none of them work. I keep getting an error that a Sources.gz can't be downloaded because it's missing, and the program won't install. Very annoying.
Found it on SourceForge: http://sourceforge.net/projects/remastersys/files/
Since Julia is based on Maverick I downloaded that version, put a blank DVD in the burner and then just double-clicked on the downloaded package. It installed fine, and put an icon to RemasterSys in the Mint menu, so I opened that and ran it. It's at 1% progress now... this might take a while.
Just in case it doesn't work, I created back-ups of my home directory and my apps with mintBackup and saved them on a portable drive. Computer rebuilding this weekend!
