> So it sounds like booleans are meant to be set by the admin if they need that sort of
thing on. In the case of samba if the admin wanted to share out user directories they
would need to turn on a boolean that would allow them to do so like
samba_enable_home_dirs.

> I see a few different files in /tmp that are labelled as tmp_t, but the ones I care
about are the krb5cc_X files. If I use kinit to generate the krb5cc file it is labelled
as user_tmp_t but if I login through ssh,local_login, gdm, etc... they get created as
tmp_t. Seeing that my daemon is responsible for kerberos login I can only guess that it
is generating them incorrectly. In my SELinux module should I have a transition for files
created in tmp to have them created as user_tmp_t or is there a better way?
