+Subject: [PATCH 1/2] add: fix virtual package id generation
+
+Fixes 37fbafcd by adding more input to the hash than just second
+grained time stamp - collisions would happen when running apk
+scripted.
+
+For virtual package the hash works only as unique identifier, so
+try to add elements that should make it unique in most cases.
+
+Fixes #10648
