On the opposite, that's a requirement for the most famous Linux based  =

platform, which is Ubuntu.

To publish an application via the Software Centre, the application have =
to  =

be installable in `/usr/opt` and to be able to be self=E2=80=91contained=
 in a  =

single sub=E2=80=91directory of `/usr/opt` [1] and the only exception to=
 this I  =

know, is the desktop file which will be written to  =

`/usr/share/applications` and even schema files needed by GSettings, hav=
e  =

to be located inside of the application's self=E2=80=91contained directo=
ry [2].
