;; This is a specification for SELinux 2.7 written in the SELinux Common
|
|
;; Intermediate Language (CIL). It refers to types that must be defined in
|
|
;; the system's base policy.
|
|
|
|
;; If you, like me, need advice about fixing an SELinux policy, I recommend
|
|
;; reading https://danwalsh.livejournal.com/55324.html
|
|
|
|
;; In particular, you can run semanage permissive -a guix_daemon.guix_daemon_t
|
|
;; to allow guix-daemon to do whatever it wants. SELinux will still check its
|
|
;; permissions, and when it doesn't have permission it will still send an
|
|
;; audit message to your system logs. This lets you know what permissions it
|
|
;; ought to have. Use ausearch --raw to find the permissions violations, then
|
|
;; pipe that to audit2allow to generate an updated policy. You'll still need
|
|
;; to translate that policy into CIL in order to update this file, but that's
|
|
;; fairly straight-forward. Annoying, but easy.
