+Strangely enough I was thinking vaguely along the same lines. My issue
+was udev specifically. Sadly working out exactly when to rebuild the
+initramfs is pretty tricky, e.g. if lvm or dm tools are updated do we
+really need them in this particular setup's initramfs? Should we rebuild
+anyway (it should be safe) and accept the unnecessary work in those
+cases? Might be a reasonable thing to do...
+
+I guess then a filetrigger could be written that checks for files
+certain locations and triggers an initrd rebuild. For the kernel it
+would only build one, but for udev, dm, lvm etc. it would rebuild all of
+them...
+
+Might confuse some people however and create cases working systems are
+hosed unnecessarily, and I'm not sure how much of real, practical
+problem it is to simply have a slightly outdated tools in the initram
+fs? Perhaps we just need to get ordering better on updates such that
+udev, lvm, dm etc. are all ordered before kernel during updates? Maybe
+that will solve 95% of the issues?
