Unable to install AM package in multi-user system environment

Steps to reproduce:

• add two user accounts in host OS (user1 and user2)
• run System UI from user1 session, do something (run/install packages)
• stop System UI
• switch to user2 session
• run System UI from user2 session
• try to install package

Observed:

$appman-controller install-package -a untitled1.pkg

Starting installation of package untitled1.pkg to internal-0...

Acknowledging package installation...

ERROR: failed to install package: could not create manifest sub-directory /tmp/minidesk/manifests/untitled1+ (code: 10)

Reason:

"/tmp" directory shared between users and can be updated (write access) only by author (owner: user1; accces: drwxr-xr-x)

Possible solutions:

• use home directory for System UI data (per-user)
• grant access for "/tmp" to all users (drwxrwxrwx)

Other multi-user scenarios can be checked also:

• switching between users without stopping System UI and logout
