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problem it is to simply have a slightly outdated tools in the initram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?
