Agreed, excellent suggestion menotu.
If I recall correctly, a couple of years ago during a reinstall, a few older files stored in /Home became incompatible with the latest version. There was concern that using our older /Home would corrupt the new install. Were not we advised to start with a new /Home and directed as to which app files were safe to copy over? At my age my memory is cloudy, so that may be incorrect, but that's what I remember.
I suspect that Tex and gang will provide the necessary directions when the time comes. The Feb PCLOS Magazine is now out but nothing of this nature listed in it's Table of Contents.
