[osgi-dev] Query on permission file

The default default (2x!) is AllPermission; this is just to get
started. However, any sane installation will set the default
permissions for a bundle to something more restricted before it
downloads any untrusted bundle.
One policy could be to read the bundle permission file and associate these
permissions with the bundle location. This is perfectly valid, and
even secure if you can ensure that only the responsible party can
install bundles and that the connection over which the bundles are
download can be trusted. This is all in the realm of the bundle
management agent and not specified in detail by OSGi, the spec only
enables such models.
Conditional Permission Admin standardized signing to solve many of the
uncertainties around operator policies. It is, like all services,
kb> That means that even if a bundle is having a permission resource,
kb> default permissions for that bundle will be AllPermissions
kb> if nobody sets the permissions. (Only permission admin present)
kb> . But I think the bundle need not be given all permissions
kb> in that case. Please let me know what should be the default permissions for that bundle.
kb> Also can you please let me know if conditional permission admin
kb> service is a mandatory service or optional as of R4?

kb>> Hello All,
