I would create packages, and therefore restrict attention to the
systems that are to be supported.

For RPM, there is a distutils bdist_rpm command which can help in
generating the RPM. OTOH, it might be actually easier to write a .spec
file and build the RPM "manually".

For .deb, there is also a bdist_deb distutils command (although not
part of the standard Python distribution), again, it is likely easier
to use the standard Debian packaging tool chain (i.e. with an
explicit debian/ subdirectory, initially populated with dh_make).

In either case, it is probably a good idea to look at source packages
to get started quickly.

FWIW, Debian does *not* put daemon programs in /usr/bin. Debian
follows the FHS, which specifies that system binaries go into
/usr/sbin. /usr/bin is limited to user programs.
