My own use case here is that I had to work around a bug in newer kernels
by running a very old one for *months*, I don't have the precise number
anymore but I think I had at least 5 or 6 kernels newer than the only
one I could use.
Is there a way to know the last time a kernel was booted and use that as
a criteria to keep it ?
This will allow removing kernels unused for months limiting the risks
that we remove a vital one.
