**Describe the enhancement**
Currently, Dracut always makes an overlayfs mounte…d when using this option take up half of available RAM. Users with very little RAM may find this to be too much, users with a lot of RAM may want substantially more storage available to them when booted in live mode. It would be useful to be able to customize this with a kernel parameter, but at the moment the only documented way of changing the overlay size is to remount the overlay with a different size. This of course is easy to forget if doing it manually, and making it persistent requires making a systemd unit (or whatever one's init system's equivalent is) to run the command on boot. Being able to set the size via a kernel parameter would make things much easier.
