Comment 1 Sven Vermeulen (RETIRED) gentoo-dev 2012-07-06 16:14:04 UTC 
How do you have it start udisks? I installed it and started dbus, but apart from dbus now running, I don't see udisks running nor do I see a failure in the avc logs...

I don't know... I didn't explicitly configure udisks. Here are some things I guess might help:

And I have thunar and gimp in my world file. I'm using XFCE, so maybe some usage of Thunar triggered it, I'm not sure yet. Hopefully that's helpful, try installing thunar and launching it and see what happens. Please let me know if you need more info.

udisk is started via xinitrc usually. This could very well be fixed with the /run changes.
Comment 4 Sven Vermeulen (RETIRED) gentoo-dev 2012-08-15 15:27:46 UTC 
From the policy sources, it looks like we should create a policy for the udisks daemon and then "dbus_system_domain(udisks_t, udisks_exec_t)" or something like that. That'll allow dbus to execute the command and transition to the domain.

I don't feel like allowing dbus to execute bin_t.
Comment 5 Sven Vermeulen (RETIRED) gentoo-dev 2012-12-03 10:53:56 UTC 
Looks like udisks is covered by devicekit. I'll try with this policy installed and see if the file contexts are ok. I'll also have the package depend on selinux-devicekit properly.
Comment 6 Sven Vermeulen (RETIRED) gentoo-dev 2012-12-09 10:43:08 UTC 
sys-fs/udisks has been updated with selinux? ( sec-policy/selinux-devicekit) dependency. Contexts in the devicekit module seem to be accurate.
