file-systems: 'file-system-needed-for-boot?' always returns #t for "/".
Reported by Nikita Karetnikov. * gnu/system/file-systems.scm (<file-system>): Rename 'needed-for-boot?' accessor to '%file-system-needed-for-boot?'. (file-system-needed-for-boot?): New inlinable procedure. * gnu/system.scm (other-file-system-services)[file-systems]: Rely on 'file-system-needed-for-boot?' to handle the "/" case. (operating-system-initrd-file)[boot-file-systems]: Likewise.
