If you create, remove or modify you own check plugins in
~/local/share/check_mk/checks then usually had to do a real core
restart with cmk -R in order to activate these changes. This is now
done automatically. Whenever you do Activate Changes then Check_MK
does a real restart on demand if it sees any modification in the check plugins.
This also helps the handling of installing and removing Check_MK packages (MKPs).
