The above statement is not true. I have only on / filesystem and I back up
/home /root /etc/ and anything else I want to backup using tar before
each upgrade. This is especially useful when you want to restore your
old home directory in the directory the installed created. Untarring
with the -k option does not overwrite the files already existing in the
directory so the new versions of the gnome configuration files (for
example) are preserved.

A wise person makes his own decisions, a weak one obeys public opinion.
