Not anymore apparently. Been running now for quite some time without these
privileges and I get no problems with it. Retry:
Mozilla/Firefox creates temporary files for its plugin support (for instance
while viewing flc streams), like /tmp/plugtmp/plugin-crossdomain.xml.
Update policy to allow it to create its own tmp type and perform a file
transition when creating a file or directory in a tmp_t location (like
/tmp).

Indeed, create_dirs_pattern is sufficient here. Retry ;-)
During startup, authdaemon creates /var/lib/courier/authdaemon and creates a
socket for communication with courier imapd and pop3d daemons.

After a quick discussion with dominique, new attempt due to two issues:
1. No need (or even forbidden) to have "role $1 types foo_exec_t"
2. Suggestion to use the raid_run_mdadm name instead of raid_mdadm_role. The
idea here is to use raid_mdadm_role for prefixed domains (cfr. screen)
whereas raid_run_mdadm is to transition and run into a specific domain
Without wanting to (re?)start any discussion on prefixed versus non-prefixed
domains, such a naming convention could help us to keep the reference policy
cleaner (and naming conventions easy).
Also, refpolicy InterfaceNaming document only talks about run, not role.
So, without much further ado... ;-)
The system administrator (sysadm_r role) needs to use mdadm, but is not
allowed to use the mdadm_t type.
Rather than extend raid_domtrans_mdadm to allow this as well, use a
raid_mdadm_role (a bit more conform other role usages).
The other users of raid_domtrans_mdadm are all domains that run in system_r
role, which does have this type allowed (as per the system/raid.te
definition), so it wouldn't hurt to use raid_domtrans_mdadm for this.

During the installation of for instance java-config, Portage wants to set
its default file creation context to root:object_r:portage_tmp_t which isn't
allowed:

This seems to be during a standard "make install" of the package but part of
Portage' sandbox usage (above error for ustr, but packages like python exhibit
the same problem.)

The attached patch allows postgresql_t domain to read selabel definition files
(such as /etc/selinux/targeted/contexts/sepgsql_contexts).
The upcoming version (v9.1) uses selabel_lookup(3) to assign initial security context
of database objects, we need to allow this reference.

postalias should stay bin_t, is manually executed (no role executes
postfix_master_exec_t as it is only to be launched through init scripts).
The postalias command is used to regenerate the aliases.db file from the
mail aliases and as such is a system administrative activity. However, by
default, no role has execute rights on any postfix_master_exec_t domains as
the domain is apparently meant only to be started from the run_init_t
domain.
