Subject: [PATCH] Add noatsecure for $1_systemd_t executing $1_dbusd_t
Date: Sat, 5 Aug 2023 11:32:41 +1000 [thread overview]
Message-ID: <ZM2muRxFrYiqARmC@xev.coker.com.au> (raw)
Add noatsecure for $1_systemd_t executing $1_dbusd_t because systemd sets
important environment variables and dbus-broker aborts with "no media" error
otherwise.
Tiny patch because this was a pain to track down and is necessary to make
Mobian usable.
