Updating the system may require immediate restart

It looks like the package management already moves packages around on an update. Since it doesn't keep the packages used open, it can happen that it won't be able to access a currently activated package anymore afterwards.

For example, the binutils package had been updated. "as" from that package could not be run anymore until a restart.

That could be improved by telling the packagefs whenever the location of an activated package changes during runtime.

Related bug that I never got around to reporting: After a "pkgman update", if you try to do anything else with pkgman (install/uninstall/etc.), package_daemon crashes.

I wonder if some of this could be alleviated by using node refs to the activated packages, such as when their entry refs change, the package kit doesn't need to worry, and can still work with the nodes themselves no matter where they moved to.

I suppose the only downside to that is that it would hold file descriptors open, if I'm understanding the BNode documentation correctly... I guess the package kit doesn't hold files open currently, hence leading to the behaviour we currently have?

package_daemon crash in being tracked at #10898.

Tested with hrev52014. This bug seems fixed as of #10898..

I don't think this one is fixed at all.
