Hello
I have found possible cause of this bug. This error occurs when i used pressed files from my boot server, but when i use other method on pressed.cfg it works without error. The other method is using this two commands cpio -di < initrd and after copying pressed.cfg in root directory of initrd find . | cpio --create --format='newc' > initrd. Possible cause may be hidden character in pressed.cfg or unsupported line in pressed.cfg.
Thank You
Have A nice day
