Currently,
...
many
...
of
...
our

modules
...
have
...
no
...
.install
...
file,
...
yet
...
they
...
set
...
Druapl
...
system
...
variables
...
that
...
would
...
get
...
left
...
behind
...
in
...
the
...
database
...
if
...
the
...
module
...
were
...
disabled/removed.

Adding

or

creating

a

blank
...
.install
...
file
...
with

just
...
this

check

something
