This makes immucore run more in parallel rather than block everything
else. We just tell sysroot.mount that eventually it will be mounted and
to wait for a bit.
This allows us to be more flexible where to run and run in parallel in
cases like cdrom in which we may do things but we need the sysroot to be
mounted already but not from us.
Also adds the initramfs stage directly in immucore and merges all the dracut config into one
Dont create sysroot, just add a timeout override so it waits for us
Dont block on the service, just make sure to finish before
initrd.target
Fix mounts from cmdline
More proper log
Store logs under the /run/immucore dir
Store rootfs and initramfs logs separated
Do not log the full stages in INFO level
Run initramfs stage in immucore directly on boot and cd/netboot
Drop systemd requirement from dracut module
