<p class="MsoNormal"><span lang="EN-US">Hi, we have been playing around more with the portable services and lots of loose thoughts came up. Hopefully we can initiate discussions.
<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">The PrivateUsers and DynamicUsers are turned off for the trusted profile in portable services but none of the passwd/group and nss files are mapped to the sandbox by default essentially preventing the sandbox to do a
user look up. Is this a use case that should be offered by the “trusted” profile or should this be handled by the services that would like to do a look-up?
<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Is there a way to have PrivateUsers=yes and map more host users to the sandbox? We have dynamic, uid based authorization on dbus methods. Up on receiving a method, the server checks the sender uid against a set of rule
files. <o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Would it benefit others if the “profile” support was moved out of the portable services and be part of the unit files? For example part of the [Install] section.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Has there been any thought about nesting profiles? Example, one profile can include other profiles in it.
<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Systemd analyze security is great! We believe it would be easier to audit if we had a way to compare a service file’s sandboxing directives against a profile and find the delta. Then score the service file against delta.
<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Thank you for your comments<o:p></o:p></span></p>
