After reflash I'm currently at CSSU-testing (installed before servers migration) and kernel-power 51r1.
Enabling extras-devel and running apt-get upgrade wanted to upgrade besides kp52 packages also: file; libmagic1; gstreamer0.10-maemo-xiph. Are they dependencies of kp52(I guess not)? If not, why are they offered to upgrade as HAM shows no upgrades when extras-devel is enabled? Is it safe to upgrade also these packages?
