now for the good things - the new system keeps backups while also automatically pruning old kernels, so you don't need chimera-prunekernels anymore; after the upgrade, you can run `chimera-prunekernels rm all` (the command will remain for a while) to ditch all the pre-transition stuff and from now on you won't have to worry about it
it also has much nicer initramfs regen behavior, centralized depmod handling, and finally no package pre/post hooks
