Hi,
There the only patch debian is applying to sepolgen:
Description: fix detection of policy loads
I am running into an issue with sepolgen. Debian ships more
than one version of the refpolicy, a default one, and a MLS enabled
one. So, the include files live in either
/usr/share/selinux/{default,mls}/include sepolgen (in
src/sepolgen/defaults.py) sets refpolicy_devel() to a single
location -- and thus, only one version of the security policy may be
supported. So, sepolgen-ifgen from policycoreutils can only work
with one policy, which may not be the one installed on the target
machine. Could this be made configurable, somehow? As far as I can
see, sepolgen's python library does not offer any way to set the
value. This change fixes that. Now you may set the path to look for
development headers in /etc/selinux/sepolgen.conf, in the variable
SELINUX_DEVEL_PATH. The builtin default will have it work on Debian
and fedora machines out of the box.
