If you are using tools provided by TeX Live, like texconfig[-sys], all
changed/generated files will go into $TEXMF[SYS]CONFIG/TEXMF[SYS]VAR.

These directories are searched before the directories containing the
files provided by TeX Live.  The reason is that the latter are
read-only on a live system, they are on a DVD.

Whether texmf-local should be searched before or after texmf-dist
is an FAQ, but there is no solution which solves all problems.  In
most cases people just put their own stuff into texmf-local and they
are aware of name clashes and use reasonable file names.  If the
default configuration is not sufficient, texmf.cnf can be customized
quite easily.  If texmf.cnf has to be customized, in most cases it
makes more sense to add directory trees to the search path instead of
changing the search order.

BTW, Zdenek's search path looks quite like mine.  Where Zdenek has
$DEVNAG I have $VNTEX.  And, curiously, both obviously point to
subversion[1] working copies. :)
