liver_ram (or rd.live.ram) parameter prevents mount of persistent home

Description of problem:
Adding "live_ram" makes impossible mounting of persistent home at LiveCD boot (any kickstart). Obviously, after the image is loaded to ram, the partition is "ejected" and is not visible for mounting home. Is there a way to disable that eject by adding parameters to livecd-iso-to-disk?

In previous version of livecdtools 17.11 you could at least unplug the usb key after image is loaded to ram and then insert it again. In this case everything worked (OS was running from RAM and persistent home was mounted from usb key). In new 18.15 version even this is not possible.

I filed a bug in bugzilla.redhat.org, but no reaction whatsoever.

Steps to Reproduce:
1. Create any standard livecd.
2. When burnign to usb stick indicate that home should be created and it's encrypted.
3. When booting, press "Tab" and add "live_ram" to kernel parameters. Home is not mounted. If not, home is mounted.

Am I the only one to use the "live_ram/rd.live.ram" parameter (which is really useful) and encrypted home? ....

Thanks for ideas
