Bug#805493: release-notes: Document how to migrate SELinux policies from the old store to the new one

[Laurent Bigonville]

Package: release-notes
Severity: normal
User: selinux-***@lists.alioth.debian.org
Usertags: selinux

Hi,

With the new SELinux userspace 2.4, the policy store has moved from
/etc/selinux/<policy_name> to /var/lib/selinux/<policy_name> (the format
of the store has also changed).

The packages from the refpolicy (selinux-policy-default and
selinux-policy-mls) should be fixed to automatically migrate the the new
store (ATM this still need to be done, see #805492)

We should probably document how to do the migration for the policies
maintained directly by the users and quickly explain the differences.

Cheers,

Laurent Bigonville

Hi,

This seems like a good idea. Unfortunately, I know next to nothing
about this, so I will need some help with writing this.

Some bits that would be helpful to me:

* What do the admin need to do to perform them migration?

* Do we have a reference (to upstream) about why this is happening?

* I assume this is only relevant for people who have installed,
enabled SELinux AND written their own SELinux policies?
- Given most probably doesn't, I will add a note so people know that
they can most likely skip the section.
- Is the "set sebool" policies also auto-migrated?

* Can the admin easily check if they need to do something?
- E.g. do we have a one line shell snippet that can reliably say
"manual migration needed" ? (It is fine if we can't, it just
intended as extra service to the admins)

* Anything else worth mentioning?
- Can it be done prior to the upgrade?
- Must it be performed after upgrade but before reboot?

Thanks,
~Niels
