Bug#390760: debian-installer: Support targeted SELinux in the installer
Package: debian-installer
Severity: wishlist
Hi,
We are at a point where we can support a targeted SELinux
policy, at least in permissive mode, I suggest that we ship SELinux
installed, but turned off by default; and a README or a short shell
script fr the local administrator to enable SELinux. Our support at
this point is better in some respects to any other distribution
(selecting and installing modular policy modules, for instance). All
the core packages support SELinux (unlike in, say, Ubuntu).
We can do this by adding selinux-policy-refpolicy-targeted,
and the dependencies, to the installer.
With the help of
apt-rdepends --dotty selinux-policy-refpolicy-targeted
I have managed to determine that the packages not already included in
Priority Standard are:

The size of the .debs for targeted policy is 2185702 Bytes.
No special configuration should be required; the default
configuration out of the box ought to work.
As shipped, the Debian kernel images have SELinux compiled in,
but disabled, a command line parameter is required to turn SELinux
on. When SELinux is turned on (by enabling it in grub), the default
policy setting are that the machine would come on in permissive mode,
using the targeted policy; so the worst case scenario is that the
there would be lots of log messages if someone "accidentally" turned
on SELinux.
I think we are ready. And shipping SELinux by default would
be a positive thing, in these days of accelerating attacks :)

Q: How many supply-siders does it take to change a light bulb? A:
None. The darkness will cause the light bulb to change by itself.
